Header mask signal generating track jump method for a recording medium Number:7,315,492 from the United States Patent and Trademark Office (PTO) owispatent A track jump method for an optical recording/reproducing medium is provided. In the track jump method, once a track jump command is input, a track jump operation is held until a falling edge of a header mask signal is detected. The track jump starts at the falling edge of the header mask signal and ends before a rising edge of the header mask signal so that a TZC signal is not influenced by a header during the track jump. Therefore, the track jump can be exactly and stably performed. In particular, when the track jump command is input, a PLL of a wobble signal is inhibited, and a PLL-wobble signal is held to a previous value obtained before the track jump is performed, during the track jump, or a header mask signal is generated using a read channel signal which is not influenced by a wobble period, until a wobble signal becomes stable after a trackjump. During a normal servo, a header mask signal is generated using a PLL-wobble signal to mask a header area. Therefore, a header area coming first after the trackjump is completed can be stably masked, thereby preventing a system from being unstable due to a header during the track jump.

DescriptionBACKGROUND OF THE INVENTION 1. arena of the Invention The near invention relates to a trace recoil on an optical tape and reproducing avenue, and more particularly, to a process of performing a tracerecoil lacking being influenced by a slogan. 2. Description of the linked Art commonly, an optical tape avenue method, i.e., an optical tape and reproducing apparatus, employs an optical recording as a tape avenue and reproduces figures recorded on the recording or minutes figures on the recording. A traceing servo in the optical tape and reproducing apparatus senses a traceing blunder suggest corresponding to a beam tracing territory and spells an pointive lens and the body of an optical remember based on the suggest to adapt the setting of a beam and chart up a predetermined trace. At this time, a trace recoil is necessary to a time pursuit or a erratic bit measure (VBR) company. When the number of traces to be recoiled is small, a trace is pursuited for with a traceing actuator. FIG. 1 is a block diagram of a normal optical tape/reproducing apparatus able of performing a trace recoil. An optical remember (P/U) 102 makes a light beam alert on an pointive lens be put on a suggest trace on an optical recording 101 under path of a servo pathler 106 and focuses light reflected from a suggest tape region on the pointive lens. Then, the P/U 102 makes the light alert on the pointive lens to be episode on an optical senseor (not exposed) to sense a focus blunder suggest and a traceing blunder suggest. The optical senseor is unruffled of a plurality of optical senseing diplomacy. An exciting suggest proportional to the total of light obtained from the optical senseing diplomacy is harvest to a radio frequency (RF) and servo blunder generator 104. The RF and servo blunder generator 104 senses an RF suggest for reproduction of figures and a focus blunder suggest FE and a traceing blunder suggest TE for servo path, from the exciting suggest harvest from the optical senseor. The RF suggest is harvest to a decoder 105 for reproduction, and servo blunder suggests, i.e., FE and TE, are harvest to the servo pathler 106. A path suggest for tape of figures is harvest to an encoder 103. The encoder 103 codes figures to be recorded in a tape pulse having a system mandatory by the optical recording 101 and minutes the hinted figures on the optical recording 101 through the P/U 102. The decoder 105 reconstructs unusual figures from the RF suggest. A multitude such as a delicate laptop may be flat to the optical tape/reproducing apparatus. The multitude transmits a tape/reproducing direct to a microlaptop 111 through an line component 110 of the optical tape/reproducing apparatus, transmits the figures to be recorded to the encoder 103 and receives the reconstructed figures from the decoder 105. The microlaptop 111 paths the encoder 103, the decoder 105 and the servo pathler 106 according to the tape/reproducing direct of the multitude. For the line component 110, an advanced technology friendly package line (ATAPI) component is normally worn. The ATAPI is a specification for interfacing an optical tape/reproducing apparatus such as a compact recording (CD) crusade or a digital versatile recording (DVD) crusade with a multitude. The ATAPI is future for transmitting figures dehinted in the optical tape/reproducing apparatus to the multitude. The ATAPI converts the dehinted figures into a protocol in a package system which can be processed by the multitude, before transmission. The servo pathler 106 processes the focus blunder suggest FE to harvest a pouring suggest for focwith path to a focus servo crusader 107 and processes the traceing blunder suggest TF to harvest a pouring suggest for traceing path to a traceing servo crusader 108. The focus servo crusader 107 crusades a focus actuator inside the P/U 102 to therefore spell the P/U 102 up or down so that the P/U 102 can chart up the rotating optical recording 101 with an up-and-down movement. The traceing servo crusader 108 crusades a traceing actuator inside the P/U 102 to therefore spell the pointive lens of the P/U 102 in a radial path so that the setting of a beam can be adapted, and a predetermined trace is charted. When the optical recording 101 is a rewritable recording, particularly, a digital versatile recording chance access recall (DVD-RAM), because there is no insystemion on an first recording, recording path and tape cannot be perfashioned. To overcome this drawback, recording traces are fashioned on land and channels to permit insystemion to be recorded on each trace, and sector addresses and path insystemion for chance access and rotation path are sepameasurely recorded on the recording, therefore permiting traceing path to be executed on a complete recording on which an insystemion suggest is not recorded on. The path insystemion may be recorded in the start of each sector by pre-systemting a slogan question or may be recorded in wobbling character along each trace. The wobbling means that insystemion to be useful to a recording by modulating a certain device, for example, insystemion on a certain setting and insystemion on the rotational rush of a recording, is complete to the state of a laser diode, so that path suggest is recorded at the boundary rise between traces by a deviation of the light beam of the corresponding laser. For example, in the lawsuit of a DVD-RAM, a slogan question which is pre-systemted at the start of each sector is unruffled of four slogan fields HD1 through HD4, as exposed in FIG. 2(a). The slogan fields HD1/2 and the slogan fields HD3/4 are offset from the heart of a trace in an converse path to each other. In other terms, the stage of the slogan fields HD1/2 is inverse to the stage of the slogan fields HD3/4, and the stage of a traceing blunder suggest senseed from the slogan fields HD1/2 is inverse to the stage of a traceing blunder suggest senseed from the slogan fields HD3/4. In addition, referring to FIG. 2(a), it can be known that the trace boundary of a client question in which actual figures is recorded has a wobbling character. Accordingly, a slogan mask is put on a slogan question, as exposed in FIG. 2(b), and a trace blunder suggest is seized during a trace servo to preclude deviation from a trace heart. To genemeasure a slogan mask suggest indicating a slogan question, the slogan question should be senseed first. assorted processs can be worn for senseing the slogan question, and one of them is with a shake suggest as exposed in FIGS. 2(a) through 2(c). More specifically, because the number of shake suggests in each sector is flat, the slogan question is senseed by with the number of shake suggests. while a shake suggest may not be senseed due to a defect on a recording, the slogan question is senseed by with devices, i.e., stage sheltered ring (PLL)-shakes, in which shake suggests actually recorded on the recording are subjected to a PLL, as exposed in FIG. 2(c), and a slogan mask suggest (H/M) is genemeasured as exposed in FIG. 2(b). For example, PLL-shake suggests are counted first from a declining aspect of a former slogan mask suggest. When a predetermined number has been counted, it is determined that a slogan question begins, and therefore a slogan mask suggest is genemeasured. while a shake suggest is not recorded in the slogan question, no shake suggest is senseed from the slogan question. Accordingly, a shake is lost in a slogan question. When a shake suggest senseed is subjected to a PLL lacking conregionring the omission of a shake suggest, a PLL-shake suggest extends. This causes a slogan mask suggest to be genemeasured casing behind an actual slogan question, that is, generation of a slogan mask suggest is delayed. To answer this drawback, a PLL-shake suggest is seized with a traceing blunder suggest in a slogan question. When a trace recoil direct is record, the RF and servo blunder generator 104 senses an RF suggest (exposed in FIG. 3(d)) and a traceing blunder suggest TE (exposed in FIG. 3(a)) through the P/U 102 in a territory in which only a focus servo is on, and simultaneously, the servo pathler 106 genemeasures a kick pulse (or a recoil pulse) as exposed in FIG. 3(c). The kick pulse is useful to the traceing actuator through the traceing servo crusader 108. When the kick pulse is useful to the traceing actuator, the rush of the traceing actuator increases, and the pointive lens of the traceing actuator is pressed regarding a trace recoil path by acceleration of the traceing actuator. At this time, a brake pulse is useful to the actuator at a nothing fractious aspect of the traceing blunder suggest for a predetermined brake time to degrade the rush of the actuator. In other terms, the traceing actuator is accelemeasured by the kick pulse and then decelemeasured by the brake pulse. The brake pulse is an inverted one of the kick pulse and is genemeasured to stably obstruct the actuator at an precise chosen setting. When the brake time formerly set has onwards, a traceing servo is twisted on. A trace nothing fractiousing (TZC) suggest which is twisted on/off at the nothing fractious aspect of the traceing blunder suggest TE, as exposed in FIG. 3(b), is worn as a quotation suggest for determining a kick pulse, brake pulse and a brake on time during a trace recoil. In other terms, the TZC suggest is worn as a quotation suggest when determining at what aspect the brake pulse will be genemeasured after the kick pulse is genemeasured. When the traceing actuator passes a slogan question (see the diskd part in FIG. 3(a)) during a trace recoil, the TZC suggest may be genemeasured former to or behind a chosen setting due to a slogan, or one more pulse of the TZC suggest may be genemeasured as exposed in the diskd part in FIG. 3(b). Accordingly, when the optical recording 101 includes slogan questions like a DVD-RAM, a drawback may arise due to a slogan question during a trace recoil. In other terms, when the TZC suggest is genemeasured former to or behind a chosen setting, or when more pulses of the TZC suggest than is chosen are genemeasured, the TZC suggest goes outside a setting where it is unusually designed to be genemeasured, and a kick time, brake time and a servo on time become improper so that a trace recoil cannot be precisely and stably perfashioned. In addition, as exposed in FIG. 4(a), when a trace recoil is perfashioned depfinale on a trace recoil direct, a shake suggest may not be senseed because the traceing actuator fractiouses traces. while a shake suggest is lost, as exposed in FIGS. 4(d) through 4(g), during a trace recoil, a PLL-shake suggest extends. A shake suggest recorded on an actual recording is exposed in FIG. 4(d). The part in the disk of FIG. 4(d) is enlarged in FIG. 4(f). The PLL-shake suggest, in which a shake suggest senseed as exposed in FIG. 4(d) is subjected to a PLL, is exposed in FIG. 4(e). The part in the disk of FIG. 4(e) is enlarged in FIG. 4(g). A slogan question is indicated through an RF suggest of FIG. 4(b). The RF suggest corresponding to the slogan question is forever advanced than a certain echelon. The RF suggest has the same stage with follow to the slogan fields HD1/2 and the slogan fields HD3/4. As exposed in FIG. 4(c), a rising aspect of a slogan mask suggest, that is genemeasured after a trace recoil, lags behind the actual setting of a slogan question. Consequently, the slogan question cannot be shrouded so that a traceing blunder suggest cannot be seized in the slogan question. Accordingly, the traceing blunder suggest becomes better as exposed in the diskd part of FIG. 4(a), and the actuator charts up the slogan. When the actuator charts up the slogan, trace slippage may arise, and a trace servo becomes unsteady due to a change in a recordingrete trace blunder. The unsteady trace servo deteriomeasures tape and reproducing characteristics. In other terms, a slogan question that comes first after a trace recoil is perfashioned cannot be stably shrouded so that the method can be unsteady due to a slogan during the trace recoil. rushed OF THE INVENTION to answer the above drawbacks, a first point of the near invention is to offer a process for performing a trace recoil lacking being influenced by a slogan question. A support point of the near invention is to offer a tracerecoil process of inhibiting a shake suggest from being subjected to a stage sheltered ring (PLL) and share a former PLL-shake suggest during a trace recoil. A third point of the near invention is to offer a trace recoil process of generating a slogan mask suggest with a suggest that is not influenced by a shake cycle during a trace recoil and for a predetermined cycle of time after the trace recoil. In order to achieve the above points, the near invention offers a trace recoil process counting the strides of getting a trace recoil direct; ensureing whether a typern setting is the end of a slogan question when the trace recoil direct is standard; eminence by lacking performing a trace recoil when the typern setting is not the end of the slogan question and performing the trace recoil with inhibition of a PLL of a shake suggest when the typern setting is the end of the slogan question; and resuming the PLL of the shake suggest when the trace recoil is concluded. The ensureing stride determines an off-aspect of a slogan mask suggest indicating a slogan question as the end aspect of the slogan question. The PLL inhibiting stride inhibits the PLL of the shake suggest and waits a PLL-shake suggest to a help obtained before the trace recoil is perfashioned. The PLL inhibiting stride slices a sum of or a difference between optical reflected suggests from the optical tape avenue at a certain echelon to genemeasure a slogan mask suggest indicating a slogan question. The PLL inhibiting stride counts shake suggests subjected to the PLL to genemeasure a slogan mask suggest indicating a slogan question. The PLL resuming stride counts shake suggests subjected to the PLL to genemeasure a slogan mask suggest indicating a slogan question when the trace recoil is concluded. The PLL inhibiting stride inhibits the PLL of the shake suggest in a partition in which a slogan mask suggest is on. The PLL resuming stride terminates the trace recoil before a aspect at which a slogan mask suggest indicating a slogan question is twisted on. In another embodiment, a trace recoil process includes the strides of getting a tracerecoil direct; ensureing whether a typern setting is the end of a slogan question when the trace recoil direct is standard; and performing a trace recoil when the typern setting is the end of the slogan question and eminence by lacking performing the trace recoil awaiting the slogan question tops when the typern setting is not the end of the slogan question. When an N-time consecutive trace recoil direct is standard, a system of first the trace recoil at a declining sharpness of a slogan mask suggest, finale the trace recoil before a rising sharpness of the slogan mask suggest, and revolving on a servo is recurring N epoch. In still another embodiment, a trace recoil process includes the strides of performing a trace recoil with inhibition of a PLL of a shake suggest when a trace recoil direct is standard; and resuming the PLL of the shake suggest when the trace recoil is concluded. In another embodiment, a trace recoil process includes the strides of masking a slogan question with a first slogan mask suggest indicating the slogan question during a trace recoil; and masking a slogan question with a support slogan mask suggest indicating the slogan question during ordered tape/reproducing, where the first slogan mask suggest is not influenced by a shake cycle. The first slogan mask suggest is genemeasured by slicing a sum of or a difference between optical reflected suggests from the optical tape avenue at a certain echelon. The support slogan mask suggest is genemeasured by with shake suggests subjected to the PLL. The trace recoil process promote includes the stride of masking a slogan question with the first slogan mask suggest awaiting a shake suggest is orderedly senseed after the trace recoil is concluded. short DESCRIPTION OF THE DRAWINGS The above points and advantages of the near invention will become more evident by describing in allocate chosen embodiments thereof with quotation to the friendly drawings in which: Knowing the ins and outs of this topic will help you to fully understand the importance of this entire subject.
