Description of the invention [Technical scope to which the invention belongs] The present invention relates to a sector arranged along a spiral track. An optical disc device capable of recording and reproducing data recording and reproduction, and an optical disc device for recording and reproducing data of this optical disc β [Previous technology] The so-called rewritable data recording and reproduction that can be produced Optical discs include optical discs with a diameter of 120 mm, optical discs with a diameter of 90 mm, phase-change discs with a diameter of 120 mm (commonly referred to as PD), etc. · In these discs, a laser light is formed to guide the laser light. The guiding groove for irradiation uses the refraction of the laser light of the guiding groove for tracking. * This guiding groove is continuously and spirally formed from the inner peripheral side to the outer peripheral side of the disc. This part of the guide trench is called a grove, and the part that is not a guide trench is called a land. In the previous optical discs, information was recorded only on either side of the ditch or lane. On the other hand, the information on such a disc is read and written in, for example, 5 12-byte units or 2048-byte units. The information unit of this group is called section. In this section, a section address showing the address of each section is allocated, information is recorded to the target address, and the information is of high reliability for reproduction, and formatted according to the predetermined section format. In this formatting, the bumps called pits are formed in the header of the sector, and the information of the sector is recorded. The section that records this section of information is called the header. As mentioned above, in the past optical discs, only recorded on either the ditch or the lane. For the header, the groove record is only formed when the groove | lane record is formed (Jing first read the back Note: Please fill in this page again.)

Description of the invention 4 ) In the alley. [Problems to be Solved by the Invention] In this way, in the conventional optical discs, information was recorded only on either the ditch or the lane, but if information can be recorded on both the ditch and the lane, it can be easily inferred that it can be achieved More recording capacity. However, in order to record information in both the lane and the ditch, how to form the segment information becomes an issue. This problem will be described below. In the conventional optical disc forming the spiral track as described above, the groove and the lane system are formed in parallel. The grooves and lanes each draw a spiral trajectory in parallel to each other. * The spiral trajectories of the grooves and lanes are formed on the disc. Therefore, the conventional optical disc structure is called a double spiral structure. It is formed in parallel with the lane. When moving from the ditch to the lane, it is necessary to make a track jump *. Therefore, to regenerate the record of information, when switching from the ditch to the lane (or when the lane is switched to the ditch), a spiral track or Tracking, it is difficult to perform continuous information recording and reproduction. Furthermore, when the disc is formatted by such a double-helix structure, the section on the groove (hereinafter referred to as the groove section) and the lane (later lane section) are the only ways to format the disc separately. This is, for example, an area CAV method that interactively records and regenerates information on adjacent alleys and trenches *, which is not suitable when formatting a disc. That is, in order for adjacent lanes and trenches to have continuous section addresses', intermittent address locations need to be removed in each circle, and only the trenches and lanes are formatted. At this time, the address from the lane to the ditch or from the lane to the ditch is continuously connected to make it coordinate with the position of the paper. Quickly use the Chinese paper standard.

In addition, since the (3 0 0 1 1 h) lane section and the recording section are Lane area, so the address number 3 0 0 1 1 h recorded in the header of the first half of the mark is the address of the sector. Also, such a jagged mark The positional relationship of the parts • If it is explained by the situation of the groove section, the relationship between the head of the first semi-marker is outside fluctuation (Wobble) and the head of the second half-marker is inside fluctuation. That is, the magnetic properties of the groove section In terms of track position, the first half of the head is set in a positional relationship that is offset by only half the track from the outer peripheral side of the disk, and the second half of the head is set by the position that is offset only by half the track. The positional relationship on the inner peripheral side is set. In contrast, for the lane section, it is the opposite of the groove section, that is, the head of the first half of the mark is the inside wave, and the head of the second half is the wave of the outside wave. Relationship. For the way that the lanes and grooves alternate between each other in the magnetic track every week, the polarity of the so-called grooves or lanes must be changed during the tracking. The timing of this polarity conversion is based on the reading of the header.

If the recording section is identified as the lane area based on the information obtained from the header of the standard, the recording section will be tracked with the tracking polarity of the lane area. Also, If, based on the information obtained from the header of the target, the subsequent recording unit is identified as a groove area, the recording unit will be tracked with the tracking polarity of the groove area. In addition, if the tracking polarity switching is described with reference to FIG. 1, * the tracking polarity switching is performed when the position where the laser light is irradiated on the magnetic disk is a mirror surface. In the case of specifying the position of this mirror face, it is also the information obtained from the standard head. That is, as long as any information included in the headers Header 1, Header 2, Header 3, and Header 4 is correctly read, the position of the mirror face can be estimated from the read position, thereby obtaining The position of a specific mirror face. For example, when the reading of Header 1 is performed normally, the number of bits is calculated from the moment the reading of Header 1 is completed. Here, since the format of the segment of the header is predetermined as shown in FIG. 3, it is planned to use a few bits (the remaining bits at the end of the readout of Header 1) to form the mirror surface. of. Therefore, as long as the number of predetermined bits since the end of the reading of Header 1 is calculated, it can be determined that laser light is irradiated on the mirror surface, and the tracking polarity is switched here. In addition, after the mirror polarity is converted to a predetermined polarity, the track or groove is tracked by the recording section. When the lane / ditch polarity is changed in this way, the above-mentioned relationship between the inside fluctuation and the outside fluctuation can be used to detect the conversion timing.

In detecting the timing of the lane / ditch polarity transition, The photodetector 24 of FIG. 4 is used. The photodetector 24 is composed of four photodetection units 24a, 24b, 24c, and 24d. Furthermore, the output signal of the photodetection unit 24a and the output signal of the photodetection unit 24b are added. The adder 2 6 c performs addition processing, and the output signal of the light detection unit 2 4 c and the output signal of the light detection unit 24 4 d perform addition processing by the adder 2 6'd. The output signal of the adder 2 6 c is supplied to the inverting input of the differential amplifier OP 1, and the non-inverting input of the differential amplifier 0 P 1 is supplied to the output signal of the adder 2 6 d. The motion amplifier OP 1 will output the signal about the focus point in cooperation with the difference between the two output signals of the adders 2 6 c and 2 6 d. This output signal is supplied to the tracking control circuit 28. In addition, this track control circuit 28 will cooperate with the track difference signal from the differential amplifier 0P1 to generate a track drive signal.

Description of the invention) The recording track direction of the disc is divided into β for explanation. In the light detection unit divided into two groups, a first light detection unit is provided corresponding to the outer peripheral side of the recording track. Yes, and set the output signal from the first light detection unit pair to A. In the photodetection units divided into two groups, a second photodetection unit pair is provided corresponding to the inner peripheral side of the recording track, and the output signal from the second photodetection unit pair is set to B. As a result, when the light beam is irradiated following the magnetic track, the output of the signal A will increase while the output of the signal B will decrease when the light beam passes through the header that fluctuates on the outer peripheral side. On the other hand, when the light beam passes through the header after the inner peripheral side fluctuates, the output of the signal B increases and the output of the signal A decreases. Here, if there is a difference between the two signals, that is, the (A_B) signal, the part fluctuating on the outer peripheral side is formed (A — B) &gt; 0, and the part fluctuating on the inner peripheral side is formed (AB ) &lt; 0, otherwise (A-B) = 0. Here, the state of (A — B) is represented by r + ”and the state of“ 0 ”(A — B) The state of &lt; 0 is represented by "0" (A-B) = 0. If the (A-B) signal output from the photodetector 24 is used, when the light beam passes through the groove section, before the light beam is irradiated toward the recording section of the groove section, the (A-B) signal output is caused by "+" Changes to "_". On the other hand, when the light beam passes through the lane section, the (A-B) signal output is changed from "one" to "+" before the beam is irradiated to the recording section of the lane section.

When the groove section at this moment is the groove section of the first section, the tracking polarity is changed from the lane polarity to the groove polarity in order to perform tracking control normally. In the same way, when the (A-B) signal output is changed from "-" to "+", the recording portion that can detect the next irradiated light beam is the recording portion of the lane segment. When the lane section is the lane section of the first section at this moment, in order to perform the tracking control normally, the tracking polarity is changed from the ditch polarity to the lane polarity. In this way, the timing of lane / ditch polarity change can be detected by using the polarity change of the (A-B) signal output.

Description of the invention k) By this, the writing possibility that can be used when the tracking polarity is switched by the segment type bit (representing such a segment type part) can be generated Timing of Section 1. In other words, the P ID section inside the header is read to determine the segment type, and the tracking polarity is switched according to the identified segment type. In addition, even when the first sector cannot be detected, the transition timing can be generated from the last final sector of the sector, or from the first sector of the final sector to which a possible sector is written. Switch tracking polarity. With the detection of the tracking polarity switching timing, the detected first segment is generally shown in Fig. 3 (b), and an error detection can be performed by adding a 2-byte IED section.

The segment address recorded at the head of the previous half mark 3 Ο Ο 1 1 h is larger than the segment address recorded at the head of the second half mark 3 〇 〇 0 0. This relationship is established in all the groove sections having the structure of FIG. 5. Therefore, by irradiating the beam on the header, the addresses of the first half PID section and the second half of the PID section can be read. The comparison of the segment address is compared. If the address of the PID section in the first half is larger, the recording section that is irradiated with the light beam later can be judged as the recording section of the groove section, so that it can be used to track the conversion of polarities. On the other hand, it is the same in the case of the lane section. For example, for the (3 00 1 1 h) lane section and recording unit, the head of the first half mark is the head of (30011h) and the head of the second half mark. It is (30022h) the header. Here, in the header part (3001 lh) of the first half header part, a first half P I D part in which the sector address 3 0 0 1 1 h is recorded is provided. In the header of the second half of the header (30022h), a second half PID section in which the sector address 30022h is recorded is provided. The sector address 3 0 0 1 1 h recorded in the head of the previous half mark is larger than the sector address 3 0 0 2 2 ί recorded in the head of the second half mark. This relationship is established in all the groove sections having the structure shown in FIG. 5. Therefore, by irradiating the beam on the header, the address of the first half P ID portion and the second half P ID portion can be read. If the addresses of the segment IDs are compared, if the address of the first half of the ID part is smaller, the recording part of the beam to be irradiated can be judged as the recording part of the lane segment, so that it can be used for tracking polarity conversion . ------------ (Please read the notes on the back before filling in this page) The paper size is applicable to China S home rubbing rate (CNS) A4 regulations (210X297 mm) -45 ·

In addition, in the (3 002 2h) groove section and recording section, the track center of the groove track is scanned by the beam spot after the tracking polarity is changed from the lane polarity to the groove polarity. ^ At this moment, when the beam passes After the above jagged head | When the tracking polarity is not converted from the lane polarity to the groove polarity, the beam spot will be controlled in pairs (30011h) lane section • recording section • or (3 0 0 3 3 h) lane area Section • One of the recording department performs tracking, which leads to the departure from the normal track tracking state. • Whether the light spot in this case is to control the tracking of that party depends on the eccentricity of the disc at that time and the track deviation. Factors such as the state of migration cannot be predicted in advance. Here, when the light spot of the light beam is caused to follow the magnetic track, a slight offset is applied so as not to hinder the recording and reproducing characteristics. That is, when the light spot of the light beam traces the spiral roadway and the groove track from the inner peripheral side to the outer circumference side of the magnetic track, it is slightly closer to the inner side of the disk than the track center of the roadway and the groove track. The size of the paper on the side of the paper applies to the Chinese National Standard (CNS) Α4 grid (2 丨 0X297 mm) {Jing M first read the notes on the back and then fill in this page)-, ιττ! -46-43 9056 Printed by the Consumer Cooperatives of the Central Bureau of Standards of the Ministry of Economic Affairs 5. Description of the invention ") for scanning. As a result, when the above polarity is not changed, it will be changed from (3 0 0 2 1 h) The lane section / recording section performs tracking control through the jagged header head toward (3 0 0 1 1 h) the lane section / recording section. After this tracking control, from (3 0 0 1 1 h) The lane section and recording section track the lanes every week, and then return to (3002 lh) the lane section and recording section. Therefore, the inner periphery of the disc is purposefully applied so as not to cause Prevents a slight shift to the extent of the recording and reproduction characteristics, and enables the beam in the beam to be tilted in the sector inversion order of the sector addresses shown by 3010h »30012h &gt;-*-30020h * 3002 lh, 3003 lh Dots can be scanned while remaining on the same track, and even when the switching of the tracking polarity cannot be performed, or when the switching of the tracking polarity cannot be performed smoothly, the point can be prevented from escaping from the normal tracking control. In FIG. 5, the update It may be that the embossed data field is displayed on the inner peripheral side of the disc. This embossed data field is a read-only data field, and is not formatted by updating and writing possible zigzag header structures. The data is recorded in the sector format of the read-only magnetic disk. In this embossed data field, the data is recorded based on the embossing formed by the uneven pits. In addition, a combination field composed of a mirror surface is provided between the embossed data field and the data field that can be updated and written. In addition, in such an embossed data field, for example, a reference signal is recorded, {#read the note on the back side first Please fill in this page again.

A4 specifications &lt; 210X297 male &gt; -47- 43 9056 A7 The Ministry of Economic Affairs, Central Bureau of Standards, Printing and Printing Co., Ltd., B7, Consumer Cooperatives. Physical formatting information, disk manufacturing information, and disk supplier information are used as a field for writing information that can be read out using a read-only player. In this way, even when the information recorded by formatting with a sawtooth-shaped header format cannot be read out by a conventional read-only player, it is still easy to identify the disk. The optical disc having the above-mentioned jagged head is most preferably used in combination with the so-called domain CLV method or domain CAV method when performing lane recording. That is, by forming a single spiral structure with a sawtooth-shaped header, it is possible to record information in lanes and grooves, thereby increasing the recording capacity. On the other hand, in terms of the domain C LV method or the domain CAV method, since the rotation speed control of the spindle motor can be simplified, it is suitable for high-speed data access. Therefore, in addition to using the domain C LV method and domain, In addition to the CAV method, coupled with the single spiral structure with the above-mentioned jagged head, the access speed can be further improved. As shown in FIG. 6, for example, in the field C LV method, * the surface of the optical disc 1 is divided into a plurality of ring-shaped fields Z0, Z1, ... * Z2 3. Further, information is recorded in each of the divided annular regions, and the information is recorded by formatting a segment of a single spiral structure having a jagged header. In addition, the number of disk rotations is switched for each divided area, so that it can be controlled at a certain linear speed β on the disk surface. As a result, information can be read at a constant linear speed, so high speed can be achieved. Data access. However, in the case of recording and reproduction across fields, '(please read the precautions on the reverse side before filling out this page) ^ This paper size is applicable to China National Standard Feng ((:?

Description of the invention 4) It is necessary to change the number of revolutions of the spindle motor. • For example, if there is a segment in the field that cannot be reproduced due to a defect in the recording surface, record In the case where the reserved fields of information to be written in its sections (ie, alternate fields) are not in the same field, recording and reproduction must be performed across fields, and the number of revolutions of the spindle motor must be changed. However, when changing the number of revolutions of the motor, the time required for the number of revolutions to reach a stable state must take a long time. As a result, the time required to store the data will be lengthened. In order to solve this defect, a reserved field is set up in each field. For example, · In the field divided into 24 parts as described above, that is, in the fields Zl, Z2, ... The reserved areas SO, S1, and S23 are provided on the outer peripheral side.
