Recording / reproducing optical discs for data recording and reproduction, and optical disc devices for recording and reproducing data of this optical disc. [Previous technology] As far as the so-called rewritable optical discs that can be recorded and reproduced are manufactured, there are optical discs with a diameter of 12 mm, optical discs with a diameter of 9 mm, and phase change discs with a diameter of 120 mm. (Commonly known as PD) and so on. In these discs, a guide groove for guiding laser light irradiation is formed, and the refraction of the laser light in the guide groove is used for tracking. This guide 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, and information is recorded to the target address. It is information with high reproduction reliability, and formatted according to the predetermined section format. In this format, information on a sector is recorded by forming bumps called pits on the header of the sector. The section that records this section of information is called the header. As mentioned above, in the previous optical discs, only one of the grooves or lanes was recorded. For the header, the grooves were recorded only in the grooves, and the lanes were recorded in the paper. This paper size is applicable.

Description of the invention (2) Yu Xiang · [Questions to be solved by the invention] In this way, in the past optical discs, only in the groove Or, either side of the lane has recorded information, but if it is possible to record information in both the ditch and the lane, it can be easily inferred that more recording capacity can be achieved. However, in order to record information on both the lane and the ditch, how to form the section information becomes a problem. The following is a description of this issue. 9 In the conventional optical discs that form a spiral track as described above, the ditch and the lane are parallel. To form. The grooves and lanes each draw a spiral trajectory in parallel with each other, so that the spiral trajectories of the grooves and lanes are formed on the disc, so that the conventional optical disc structure is called a double spiral structure. In this double helix structure, the trench and the lane are formed in parallel. When moving from the trench to the lane, the track must be jumped. Therefore, the information record is regenerated, and the channel is switched from the trench to the lane (or ), Need spiral track or tracking * It is difficult to perform continuous information recording and reproduction. Printed by Zhengong Consumer Cooperative of the Central Government Bureau of the Ministry of Economic Affairs {Please read the _ Cautions on the reverse side and fill out this page). Furthermore, when the disc is formatted by such a double spiral structure, the section on the groove (Hereinafter referred to as the ditch section) and lanes (hereinafter referred to as the lanes section) are only methods of formatting them separately. * This is, for example, the area CA V method to interactively record and reproduce information on adjacent lanes and trenches. It is inappropriate to format the 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 well-being from the lane to the ditch or from the ditch to the alley is continuously connected to coordinate its position λ This paper size is applicable to the Chinese national standard (CNS} Α4 size (210X297 mm) ~ ¢ 422972 a7 __B7__ 5. Description of the invention (3) When formatting, there will be difficulties in formatting. Moreover, when recording information is reproduced, the movement from lane to groove or groove to lane cannot be performed smoothly, disc rotation wait will occur. This invention prevents the realization of continuous information recording and reproduction. The present invention is made to solve the above-mentioned problems, and as its purpose, it can provide a high-capacity recording capacity and high-speed access speed, and can provide high-reliability continuity.

Here, the laser light can be modulated to a signal of a predetermined format. However, the format circuit 49 is based on the inscription operation described later. To perform laser light modulation, the beam modulation system 4 4 is controlled. Next, the laser beam is formed by a beam shaping system 4 5 through a point hole or a gap, and the beam diameter or shape is adjusted. At this point, the adjustment of the laser light is ended, and the beam shape can be confirmed in the beam monitoring system 46. The laser light system is further guided to the mirror surface 47, and is focused and irradiated onto the optical recording original disk 40 through the objective lens 48. To do this, the optical recording master 40 is, for example, a glass disc. A photosensitive coating (photoresist) is coated on the glass disc, and the surface of the photosensitive coating is irradiated with laser light. When the portion exposed by the laser light is etched, it is concave. "In order to shape the surface shape formed by the irradiation of the laser light into a desired concave-convex shape, record the grooves and format patterns." Whichever prevails, a stamper is made. During the engraving, the glass disc 40 is rotated, for example, by a rotation means 39 such as a motor. Further, the optical pickup having an objective lens 48 for irradiating laser light at a predetermined position on the glass disc 40 is moved at a constant speed from the inner peripheral side to the outer peripheral side of the glass disc 40. At the time of engraving * The optical pickup rotates every 1 disc, and moves at the same speed from the inner peripheral side to the outer peripheral direction in proportion to the track interval. * With this movement, the laser light irradiation position is moved. Through the optical pickup thus moved, the part that irradiates the laser light is a groove. The part that is not irradiated is a lane. In the header, the point of the laser light is extinguished to form a concave-convex pit.

Description of the invention (33) Only offset by half the gauge The positional relationship of the inner peripheral side of the magnetic disk is set. In contrast, in the case of the lane section, it is the opposite of the situation in the groove section, that is, the relationship between the head of the first half of the mark is the inner wave and the head of the second half of the mark is the outer wave. For the method of alternately switching lanes and grooves in the magnetic track every one week, the polarity of the so-called trenches or lanes must be switched when tracking. The timing of this polarity conversion is based on the reading of the header. That is, according to the information obtained by reading the header, before determining the track of the recording section following the header, the recording section is identified as a lane area or a groove area, and then converted into a predetermined area. polarity. If the recording section after identification is based on the information obtained from the standard header, the recording section will be tracked with the tracking polarity of the lane section. * If the recording section after identification is based on the information obtained from the header of the target, the recording section will be tracked based on the tracking polarity of the groove section. Also, the tracking polarity will be described with reference to FIG. 1 If it is switched, the tracking polarity is switched when the position where the laser light is irradiated on the disc is the 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 header Headerl, Header2 * Header3 * Header4 is correctly read, the position of the mirror face can be estimated from the read position *, thereby specifying the mirror face Position · For example, when the reading of Headerl is performed normally, the number of bits is calculated from the moment the reading of Headerl ends. Here, the paper size of the header section is subject to China National Standards (CNS) A4 this grid (210X297 mm) --------- clothing ------ 1T ------ Λ {Please read the precautions on the back before filling this page) -36-Economy The Ministry of Science and Technology of the People's Republic of China, the Procurement and Cooperation Department Du Yinzhuang 4 2 2972 at? B7 V. Description of the Invention (34) The formatting is ordered as shown in Figure 3, so it is determined by the number of bits (Headerl's final position) Remaining bits on the surface) to form the mirror surface * is also predetermined. Therefore, as long as the number of predetermined bits since the end of the reading of Headerl is calculated, it can be determined that laser light is irradiated on the mirror surface, and here Line M tracks the polarity transition. In addition, after the mirror surface has changed the tracking polarity to a predetermined polarity, the track or groove recording section is tracked. 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 the following, the configuration for detecting the lane / ditch polarity switching timing using the relationship between the inside fluctuation and the outside fluctuation will be described. In the timing of detecting the polarity change of the lane / ditch, the photodetector 2 4 of FIG. 4 is used »The photodetector 24 is composed of four parts of the photodetection units 24a, 24b, 24c, and 24d. In addition, the output signal of the light detection unit 2 4 a and the output signal of the light detection unit 2 4 b are added by the adder 2 6 c, and the output signal of the light detection unit 2 4 c and the light detection unit The output signal of 2 4 d is added 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 motor amplifier 0 P 1 will output the signal related to the focus point in accordance with the difference between the two output signals of the adders 2 6 c and 2 6 d * and supply this output signal to the tracking control circuit 2 8 · Also, this track control circuit 2 8 will cooperate with the track difference signal from the differential amplifier 0P 1 to make a track drive signal.

Description of the invention (35) Supply the track driving signal output from the tracking control circuit 2 8 to the driving coil 11 in the tracking direction, or use the track control circuit 2 8 The track difference signal is supplied to the linear motor control circuit 8 'to perform tracking control. Here, if the light detection unit 2 4 a is divided into a first light detection unit pair consisting of the light detection unit 2 4 a and the light detection unit 2 4 b, and the light detection unit 2 4 c and the light detection unit 2 If the second photodetection unit pair constituted by 4d, the two photodetection unit pairs will be divided along the recording track direction of the disc. For explanation, in the photodetection units divided into two groups, a first photodetection unit pair is provided corresponding to the outer peripheral side of the recording track, and the output signal from the first photodetection unit pair is set to A. Further, 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 ^. When the light beam is caused to follow the magnetic track and irradiate, when the light beam passes through the header that fluctuates on the outer peripheral side, the output of the signal A will increase and the output of the signal B will decrease.

Conversion of the invention description (41), ie * For example, for the (30000h) groove section and recording section, the head of the first half of the head is the head of (3001 lh), and the head of the second half of the head _ (30000h). Here, the (_ 3 00 1 1 h) In the header, set a record of the first half of the PID section 3 00 1 1 h. Also, in the header of the second half (3 0 0 0 Oh), set a The PID section of the second half of the segment address 30000h is recorded. / The segment address 3 0 0 1 1 h recorded in the header of the previous half mark It is larger than 値, which is recorded in the sector address of the second half of the header at 3 0 0 0 h. This relationship holds in all the groove segments having the structure shown in FIG. 5. Therefore, by using the Beam irradiation, comparing the address of the first half of the P ID section with the address of the second half of the P ID section, and comparing the addresses of these sector addresses. If the address of the first half of the P ID section is larger, you can After that, the recording portion irradiated with the light beam is determined to be the recording portion of the groove section, so that it can be used for tracking polarity conversion. On the other hand, the same is true in the lane section.

Description of the invention (42) is larger than 値, which is the address of the sector recorded at the head of the second half of the mark, 30 00 2 h. This relationship holds in all the groove sections having the constitution of FIG. 5. Therefore, by irradiating the beam on the header, the address of the first half of the PID section and the address of the second half of the PID section can be read out, and the 値 of these section addresses is compared. When it is small, the recording section to be irradiated with the light beam later can be judged as the recording section of the lane section, so that it can be used for tracking polarity conversion. Here, the case where the above-mentioned switching of the polarity of the tracking cannot be performed smoothly, or the switching of the tracking polarity cannot be performed as desired, and the case where the track is automatically tracked will be explained. For example, in the first section shown in FIG. 5, when the tracking is performed by a light beam from the (30021 h) lane section • recording section to the (30022h) groove section • recording section, it is usually as described above. As mentioned above, in the (3 0 2 lh) lane section and recording section, the track center of the lane is scanned by the light spot of the beam * In addition, the (30 0 3 3h) header and (3 0 0 2 2 h) The zigzag headers formed by the headers are used to track the beam along the centerline of the headers.

At this moment * After the beam passes through the above-mentioned jagged head, the tracking polarity does not change from the lane polarity to the groove polarity, the light spot of the beam will be controlled in pairs (30011h) lane section • recording section, or (30033h) lane section • One of the recording department traced, which caused the deviation from the normal f I-1 ^ 1 ^^^ 1--1 nn I ^ I-tn-" * j (锖 Please read the note on the back before filling this page ) This paper scale uses the Chinese National Vehicle (CNS) grid (210X297 mm) -45- A7 B7 Printed by the Shell Consumer Cooperative of the Central Sample Rate Bureau of the Ministry of Economic Affairs 5. Tracking status of the invention description (43) . Whether the light spot in this case is to control the tracking of that side depends on factors such as the eccentric state of the disc at that time and the state of track deviation, and cannot be predicted in advance. Here, when the light spot of the light beam is traced to the magnetic track, a slight shift that does not hinder the recording and reproduction characteristics is applied. That is, when the light spot of the light beam comes from the inner peripheral side of the magnetic track to the outer peripheral side When chasing the spiral lane and groove tracks, the scanning is performed at a position slightly closer to the inner peripheral side of the magnetic disk than the track center of the lane and groove tracks. In this way, when the tracking polarity is not changed as described above, the track will be traced from the (3002 lh) lane section / recording section to the (3 00 1 1 h) lane section / recording section via the jagged header. control. And after this tracking control, the track section from the (300 1 lh) lane section • recording department will track the track every week, and then return to the (300 2 lh) lane section * recording section. Therefore * by intentionally applying a slight shift on the inner peripheral side of the optical disc so as not to hinder the recording and reproduction characteristics, 30011h * 30012h... 3 0 0 2 0 h «30021h, 30031h The sector order of the sector addresses allows the beam spot to be scanned while maintaining the same magnetic track, and even when the polarity of the tracking cannot be switched, or it is not smooth When switching the tracking polarity, it can still prevent the tracking control from escaping. In FIG. 5, an embossed data collar t- is displayed on the inner peripheral side of the disc in the field of update writing data with the above-mentioned jagged header structure.

Description of Invention (44) • This embossed data field is for read-only data, not for recording data by updating the sector formatting of the jagged header structure that may be written, but for the read-only sector format of the disk To record information. And, in this embossed data field, the data is recorded based on the embossing i formed by the uneven pits. Furthermore, a combination area consisting of a mirror surface is provided between the embossed data area and the data area that can be updated and written. In the field of such embossed data, for example, reference signals, physical formatting information, disk manufacturing information, and disk supplier information are recorded, and it is used as a conventional read-only player to read information. In the writing field ", even if it is impossible to read the information recorded in the format of the sector structure with a zigzag header by a conventional read-only player, it is still easy to perform magnetic recording. Identification of dishes. Furthermore, it is desirable that the optical disc having the above-mentioned jagged head is used in combination with the so-called domain CLV method or domain CAV method when performing lane recording. That is, * by the formation of a single spiral structure with a sawtooth-shaped header, information can be recorded in the lanes and grooves to increase the recording capacity, and the data can be comprehensively recorded on the magnetic disk in a short time. Access> On the other hand, in terms of the domain CLV 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. In this way, in addition to the use of the domain CLV method and the domain CAV method, coupled with the single spiral structure having the above-mentioned sawtooth header, the access speed can be further improved. As shown in Figure 6, generally, for example, in the field C LV method, the surface of the disc 1 is divided into a plurality of ring-shaped fields Z0, Z1... Z2 (please read the note on the back first) Please fill in this page again on this page.) This paper size is not used in China.

In addition, information is recorded in each of the divided ring-shaped fields, and the information is formatted by a single spiral structure segment with a jagged header. Recording ”and • Switching the number of disk rotations / for each divided field allows control to a certain linear speed on the disk surface. This makes it possible to read information at a constant linear speed, so High-speed data access. However, in the case of recording and reproduction across fields *, 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, recording Reserved areas of information that must be written in its section ) When not in the same field, recording and reproduction must be performed across fields, making it necessary to change the number of revolutions of the spindle motor. The time must take a long time. As a result, the access time of the data will be lengthened. "In order to solve this defect, reserved areas are set up in various fields. For example, in the above field divided into 2 4 parts, That is, in the areas Z1, Z2, ..., Z23, the reserved areas SO, S1, ..., S23 are provided on the outer peripheral side of each area, respectively. ^^ 1 m ^^ 1 m ^ ^ 1 I-mm (please fill in this page before the WT »Notes on the back page) This paper size is applicable to China Bracelet Countries # 准 （〇15} 八四 standards < 格 （2 丨 0 > < 297 mm) -48- 4 229 7 2? at B7 V.

That is, the previous semi-standard header HF 1 will display The address information shown above for the second half of the header HF 2 and the address information for the one-week difference of the magnetic track "Also, the previous half of the header HF1 is for the RF 6 of the recording section RF (#) where the groove section # (m) is formed. In terms of position, it is formed at a position where the outer peripheral side moves only a half gauge distance. Here, the recording section RF6 of the groove section # (m) is adjacent to the recording section RF2 of the lane section # (m + N). form. That is, the recording section RF 6 of the groove section # (m) is formed on the inner peripheral side with a distance of only one gauge for the recording section RF 2 of the lane section # (m + N). Also, the former semi-standard head HF 1 and the latter semi-standard head HF 2 are continuously formed according to the above-mentioned grooves, and the former semi-standard head HF 1 and the second semi-standard head HF 2 are used in this paper. ) A4 * t grid (210 × 297 mm) {Please read the note on the back, and then fill in this page) Order -53- ^ 422972 at f B7 5. The Header3 of the invention description (51) will be arranged close to it. With this configuration, the front half-marker head HF 1 and the rear half-marker head HF 2 will be paired with each other to form a sawtooth-shaped header structure. In addition, the recording section RF 1 of the lane section # (m_l) whose address is shown based on the previous section number of the recording section RF6 of the groove section # (m) is related to The beginning of the header (the second half of the header HF 2) of the groove section # (m), that is, between the header and the Header 3, is formed in the groove with the space occupied by the first half of the header HF1. The recording section RF 6 of the segment # (m) is on the same track. Similarly, the groove section # (m + N_l) of the address indicated by the section number # (m + N) preceding the section number of the recording section RF2 of the lane section # (m + N) The recording section RF7 is attached to the beginning of the header section (front half header HF 1) of the lane section # (m + N), that is, it is close to the Headerl section to form the lane section # (m + N) The recording section RF2 is on the same track.
