Description

  The present invention relates to an optical information recording medium, an optical information recording / reproducing apparatus and a control method thereof, an optical information recording / reproducing program, and a computer-readable recording medium, and more specifically, has two or more information recording layers. The present invention relates to a multilayer optical information recording medium in which an information recording layer having recording characteristics different from those of other layers exists among the plurality of information recording layers.

  In recent years, an increase in recording capacity of optical information recording media has been demanded for enormous information processing such as images.

  As one method for improving the recording capacity of the optical information recording medium, a multilayer information recording layer of the optical information recording medium can be considered. For example, at present, a multilayer optical information recording medium having up to two information recording layers in a DVD (Digital Versatile Disc), a BD (Blu-ray Disc; registered trademark), etc. is standardized and sold.

  By the way, in a multilayer optical information recording medium having two or more information recording layers, in order to reproduce information recorded on the information recording layer far from the reproduction light incident side, the one closer to the reproduction light incident side is used. Since it is necessary to transmit the reproduction light in the information recording layer, there is a problem that the reflectance of the information recording layer closer to the reproduction light incident side needs to be set low. There is also a problem that the intensity of the return light from the information recording layer farther from the reproducing light incident side becomes smaller as the number of layers increases.

  Due to the existence of such problems, it is particularly difficult to increase the number of information rewritable information recording layers, and at present two layers are limited.

  Therefore, in recent years, in addition to the information rewritable information recording layer, an information recording layer in which various contents are recorded and a reproduction-only information recording layer that can only be reproduced or an information recording layer that can be additionally recorded are added. Thus, an optical information recording medium (hereinafter referred to as “hybrid optical information recording medium”) having an improved recording capacity has been demanded.

  Hereinafter, the rewritable information recording layer is referred to as an RE (RE-writable) layer, the reproduction-only information recording layer is referred to as a ROM (Read Only Memory) layer, and the additionally recordable information recording layer is referred to as an R. Called the (Recordable) layer.

  As an example of the prior art related to such a hybrid optical information recording medium, in Patent Document 1, in an optical disc having two or more layers, a layer that is a predetermined distance from the incident surface of the reproduction light is an RE layer, and a layer that is closer than the predetermined distance An optical disc with a ROM layer is disclosed.

  The optical disk disclosed in Patent Document 1 has the above-described structure so that the mixed state of the recorded state and the unrecorded state in the RE layer does not affect the reproduction of the ROM layer.

  By the way, in an optical information recording / reproducing apparatus for recording / reproducing information on a hybrid optical information recording medium, the optical information recording medium is composed of how many information recording layers, and what recording characteristics each information recording layer has. The identification information is used as information indicating the structure of such an optical information recording medium.

  Further, according to Non-Patent Document 1, there is a description that identification information of a commercially available BD disc is provided in a layer farthest from the incident surface of the reproduction light.

  However, in the conventional hybrid optical information recording medium, when the identification information is provided in a layer farthest from the incident surface of the reproduction light, for example, the incident of the reproduction light disclosed in Patent Document 1 In an optical disc with the RE layer on the back side and the ROM layer on the front side, it is necessary to first access the identification information on the farthest RE layer.

  Then, when a software program or the like for operating the optical information recording / reproducing apparatus is recorded in the ROM layer, the identification information of the RE layer is read first, and the user area of the same RE layer is accessed as it is, and then Since the ROM layer is accessed, there is a problem that the processing time from reading the identification information to starting the software program becomes long.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
Embodiment 1 of the present invention will be described below with reference to FIGS.

[1. Configuration of optical information recording medium]
First, based on FIG. 1, the structure of the optical disk (optical information recording medium) 2 which is Embodiment 1 of this invention is demonstrated. FIG. 1 is a schematic diagram conceptually showing an optical disc 2 of the present embodiment.

  As shown in FIG. 1, the optical disc 2 of this embodiment includes at least a RE / R layer (first information recording layer) 4 and a ROM layer (second information recording layer) 5, and each of these information recording layers. This information can be read out by reproduction light.

  In the optical disc 2, the information recording layer includes only the RE / R layer 4 and the ROM layer 5, but the information recording layer may include three or more layers. The RE / R layer 4 may be either an RE layer or an R layer.

  By the way, in the ROM layer, for example, information may be recorded by forming a prepit row in a concavo-convex shape on an interface of different materials. Therefore, in the following, in the case of the ROM layer, it may be said that information is recorded on the “information recording surface”.

  On the other hand, in the case of the RE layer or R layer, information is recorded by changing the physical properties of the information recording area in the medium surface direction of the information recording layer, for example. Therefore, hereinafter, in the case of the RE layer or the R layer, it may be said that information is recorded in the “information recording area”.

  That is, as described above, the “information recording layer” includes an information recording area or information recording surface on which information is recorded, and is a single film or a multilayer film including a reflective film or a recording film having specific recording characteristics. Or a predetermined range in the medium surface direction (in-plane direction of the incident surface of the reproduction light) at the interface between the two layers.

  As described above, the “information recording layer” is complicated to describe separately when information is recorded on the “information recording surface” and when information is recorded on the “information recording area”. Hereinafter, as a general rule, “information is recorded in the information recording layer” will be referred to.

  The information recorded on the optical disc 2 is an optical disc apparatus (optical information recording / reproducing apparatus) described below when information is recorded in advance when the optical disc 2 is shipped, when information is recorded by the user after shipment, and after shipment. This is a concept including a case where information is recorded in one operation.

  The RE layer is a so-called rewritable information recording layer and is an information recording layer capable of rewriting information.

  The R layer is a so-called additional recording type information recording layer, and is an information recording layer that can only record information.

  Furthermore, the ROM layer is a so-called read-only information recording layer, and is an information recording layer that can only read information.

  That is, the optical disc 2 is a so-called hybrid optical information recording medium in which information recording layers having different recording characteristics such as a ROM layer, an RE layer, and an R layer are multilayered.

  Further, “only additional recording is possible” means that information can be read and only additional recording can be performed during recording.

  As shown in FIG. 1, the RE / R layer 4 includes an identification information recording area 41, a management information recording area 42, and a user recording area 43.

  In the identification information recording area 41, various identification information indicating the structure of the optical disc 2 is recorded in advance.

  In the management information recording area 42, management information for managing the recording and reproduction of information on the optical disc 2 is recorded in advance.

  The user recording area 43 is a recording area where the user can record (or additionally record) desired information.

  As will be described below, in the optical disc apparatus 1, the optical information recording medium such as the optical disc 2 is composed of how many information recording layers, and what recording characteristics each information recording layer has. The “identification information” is information indicating the structure of such an optical information recording medium. In this embodiment, it is specified (identified) from the identification information that the RE / R layer 4 and the ROM layer 5 are present and that the identification information is in the RE / R layer 4.

  Specific examples of the identification information include the disc layer type (reproduction-only type, write-once type, rewritable type), disc size, disc version (related to speed, etc.), disc recording / reproduction shown in FIG. Standard conditions, servo polarity, recording mark polarity, disc-specific number, etc., but the recording order (or arrangement method) of these identification information on the identification information recording area 41 may be arbitrary. . These recording orders are usually determined by standards and the like.

  Here, in the optical disc 2 of the present embodiment, in addition to the normal identification information as described above, an interlayer movement flag (interlayer movement permission information) is recorded in the identification information recording area 41.

  The flag for interlayer movement indicates that the interlayer movement (hereinafter simply referred to as “interlayer movement”) from the identification information recording area 41 included in the RE / R layer 4 to the ROM layer 5 at the light spot position of the reproduction light is permitted. This information indicates that it is not permitted.

  More specifically, when the flag for interlayer movement is set to “0”, the interlayer movement from the identification information recording area 41 included in the RE / R layer 4 at the light spot position of the reproduction light to the ROM layer 5 is performed. Indicates that is not allowed.

  On the other hand, when the flag for interlayer movement is set to “1”, it indicates that interlayer movement is permitted.

  Even when the interlayer movement flag is set to “1”, the interlayer movement may be performed immediately after the interlayer movement flag is recognized, or the interlayer movement is not necessarily performed immediately after the interlayer movement flag is recognized. Also good. In other words, the flag for interlayer movement is information for recognizing that the interlayer movement is permitted or not permitted. After the interlayer movement flag set to “1” is recognized, the identification information recording is performed. Interlayer movement may be performed at any time until all the information recorded in the area 41 is read.

  Further, the position where the flag for interlayer movement is recorded may be recorded anywhere as long as it is between the recording start position and the recording end position of the information in the identification information recording area 41. If the flag for interlayer movement is recorded at the information recording end position in the identification information recording area 41, it is set to “1” after reading all the information recorded in the identification information recording area 41. The interlayer movement is performed immediately after the interlayer movement Flag interlayer movement is recognized.

  In addition, when the flag for interlayer movement is set to “0”, a normal reproduction operation that does not perform interlayer movement may be performed.

  The setting for setting the value of the flag for interlayer movement to “0” or “1” may be set by the user via the operation unit 7 described below, or will be described below. When the optical disk 2 or the like is loaded in the optical disk device 1 to be performed, the disk management unit 21 described below may be set.

  Therefore, for example, when the flag for interlayer movement set to “1” is recognized while reading the identification information recorded in the identification information recording area 41 in the RE / R layer 4 in advance, the identification information When the structure of the optical disk 2 described below is configured to perform a predetermined interlayer movement at the stage where the structure of the optical disk 2 can be specified by reading, identification information can be acquired and the structure of the optical disk 2 can be specified. Thereafter, without moving the light spot to the same RE / R layer 4 as it is, it can be moved to the ROM layer 5 and information (for example, a program such as software) recorded on the ROM layer 5 can be read.

  FIG. 1 conceptually shows the above interlayer movement, and shows a state in which the spot position of the reproduction light from the optical pickup 12 moves from the interlayer jump start position SP to the interlayer jump end position EP. Show.

  Here, the interlayer jump start position SP may be a position on the identification information recording area 41 when the structure of the optical disc 2 is specified from the identification information recorded in advance in the identification information recording area 41. When reading identification information from the inner circumference side (left side of the optical disk) of the optical disc 2 toward the outer circumference side (right side of the paper) of the optical disk 2, the rightmost position on the identification information recording area 41 (all the identification information is reproduced). Equivalent to the stage, but it is assumed that there is no empty area in the identification information recording area 41). Further, any position between these two positions may be used as the interlayer jump start position SP.

  On the other hand, the interlayer jump end position EP may be any position as long as it is on the information recording surface of the ROM layer 5, but from the acquisition of the identification information until the program recorded in the ROM layer 5 is started. From the viewpoint of shortening the processing time, it is preferably either the end of the information recording surface on the inner peripheral side or the end of the information recording surface on the outer peripheral side.

  As described above, according to the optical disc 2, it is possible to shorten the processing time from the acquisition of the identification information until the program recorded in the ROM layer 5 is started.

[2. Configuration of optical information recording / reproducing apparatus]
Next, the configuration of the optical disc apparatus (optical information recording / reproducing apparatus) 1 according to the first embodiment of the present invention will be described with reference to FIGS. In addition, [2. Configurations other than those described in [Configuration of optical information recording / reproducing apparatus] are described in [1. Configuration of optical information recording medium]. For convenience of explanation, [1. The members having the same functions as those shown in the drawing of the configuration of the optical information recording medium] are given the same reference numerals, and the description thereof is omitted.

  FIG. 2 is a block diagram showing a schematic configuration of the present embodiment of the optical disc apparatus 1.

  As shown in FIG. 2, the optical disc apparatus 1 mainly includes a storage unit 3, a disc loading recognition unit 6, a recording / reproducing circuit group 10, an optical head 11, an optical pickup 12, and a control unit 20.

  The recording / reproducing circuit group 10 mainly includes a pickup driving circuit 13, a laser driving circuit 14, and a reproducing circuit 15.

  The optical disk apparatus 1 is an apparatus for recording and reproducing information with respect to an optical information recording medium such as a DVD or a BD including the optical disk 2.

  As shown in FIG. 2, in the optical disc apparatus 1, the control unit 20 moves the optical pickup 12 through a pickup drive circuit 13 to a track (not shown) of the rotating optical disc 2.

  The optical pickup 12 is provided with an optical head 11. Then, the control unit 20 sets recording conditions via the laser drive circuit 14 and irradiates the recording part of the optical disc 2 with a recording laser beam from the optical head 11, whereby information is recorded on the track of the optical disc 2. It is like that.

  Further, in the optical disc apparatus 1, the control unit 20 moves the optical pickup 12 to the recording part of the optical disc 2 via the pickup drive circuit 13. Then, the control unit 20 irradiates the optical disc 2 with a reproduction laser beam from the optical head 11 via the laser drive circuit 14.

  The reflected light detected by the optical head 11 is converted into a reproduction signal by the reproduction circuit 15 and input to the control unit 20. As a result, the optical disk apparatus 1 reproduces information recorded on the track of the optical disk 2.

  The optical disc apparatus 1 is provided with a disc loading recognition unit 6. The disk loading recognition unit 6 is for detecting loading of the optical disk 2 and can be exemplified by various sensors, for example, but any sensor can be used as long as it can detect loading of the optical disk 2. .

  Further, the disc loading recognition unit 6 outputs the detected result to the control unit 20 as a detection signal.

  The operation unit 7 is used by the user to input various operation commands to the optical disc apparatus 1, and examples thereof include operation buttons and their interfaces.

  Next, based on FIG. 3, the detail of the main parts (the control part 20 etc.) in the optical disk apparatus 1 is demonstrated. FIG. 3 is a block diagram showing a configuration of a main part in the optical disc apparatus 1.

  As shown in FIG. 3, the storage unit 3 is a recording unit in which various types of information such as programs and data are recorded in advance or various types of information are recorded. The storage unit 3 is preferably configured by a RAM (random access memory), but may be configured to use a ROM together.

  The storage unit 3 mainly includes an identification information reproduction data storage unit 31, a ROM reproduction data storage unit 32, and a software program storage unit 33. Needless to say, information other than the information recorded in each storage unit may be recorded in the storage unit 3.

  For example, as described below, the above-described interlayer movement Flag is generated, and information for recording on an optical information recording medium that does not have the interlayer movement Flag, or the interlayer movement Flag is “0” or “1”. It is assumed that various information such as information for setting the value of the value, a predetermined interlayer jump start position SP for interlayer movement, and an interlayer jump end position EP are also recorded in the storage unit 3 or recorded in advance.

  In the identification information reproduction data storage unit 31, reproduction data of identification information recorded in the identification information recording area 41 of the RE / R layer 4 is recorded.

  The ROM reproduction data storage unit 32 stores a program (for example, OS: operating system) for controlling the operation of the optical disc apparatus 1 recorded in advance in the ROM layer 5 and other various data.

  The software program storage unit 33 stores a program for operating the optical disk device 1 recorded in advance, a program obtained from reproduction data of the ROM layer 5, or application software.

  Next, based on FIG. 3, the detail of the control part 20 which is the principal part of the optical disk apparatus 1 of this embodiment is demonstrated.

  As shown in FIG. 3, the control unit 20 mainly includes a disk management unit 21, a reproduction control unit (reproduction control unit, identification information reproduction control unit, interlayer movement control unit) 22, a pickup control unit 23, a laser control unit 24, software A program management unit 25 and a recording control unit (recording control means) 26 are provided.

  The disc management unit 21 receives a detection signal indicating that the optical disc 2 has been loaded from the disc loading recognition unit 6 or specifies the structure of the optical disc 2 from the identification information acquired from the optical disc 2 to thereby reproduce the reproduction control unit. 22, the software program management unit 25, the recording control unit 26, and the like control operations.

  The reproduction control unit 22 mainly includes an identification information reproduction instruction unit (identification information reproduction control unit) 221, an interlayer jump instruction unit (interlayer movement control unit) 222, and a reproduction data processing unit 223.

  The reproduction control unit 22 operates the identification information reproduction instruction unit 221, the interlayer jump instruction unit 222, and the reproduction data processing unit 223 to acquire identification information from the optical disk 2 or acquire data obtained by reproducing the ROM layer 5 of the optical disk 2. Control is performed.

  The identification information reproduction instruction unit 221 instructs the pickup control unit 23 and the laser control unit 24 to control reproduction of identification information recorded in the identification information recording area 41 of the optical disc 2. Thereby, the optical disc apparatus 1 can acquire the identification information, so that the structure of the optical disc 2 can be specified.

  When the structure of the optical disc 2 is specified by the disc management unit 21, the interlayer jump instruction unit 222 receives a notification to that effect (medium structure specification notification) and information on the structure of the optical disc 2 from the disc management unit 21. Then, the pickup control unit 23 and the laser control unit 24 are instructed to perform control to move the light spot position of the reproduction light from the above-described interlayer jump start position SP to the interlayer jump end position EP.

  In addition, [1. In the configuration of the optical information recording medium], the flag for interlayer movement has been described, but the optical disk apparatus 1 of the present embodiment is configured to control interlayer movement by using the flag for interlayer movement recorded on the optical disk 2. Alternatively, it may be configured to perform interlayer movement under the control of the optical disc apparatus 1 on an optical information recording medium that does not have an interlayer movement Flag.

  For example, when the interlayer movement is performed under the control of the optical disk device 1, the interlayer jump instruction unit 222 may be operated with the disc management unit 21 as a trigger when the structure of the optical information recording medium is specified.

  Thereby, when the structure of the optical information recording medium is specified from the identification information, the light spot position can be moved between the layers.

  Further, the reproduction data processing unit 223 processes various reproduction data transmitted from the reproduction circuit 15 (for example, reproduction signal correction processing, analog / digital conversion, etc.), and the reproduction data processed in the storage unit 3. Is to be recorded.

  Further, the reproduction data processing unit 223, for example, temporarily records a software program recorded in the ROM layer 5 in the software program storage unit 33, and notifies the software program management unit 25 that the software program has been temporarily recorded. For example, the management unit 25 is operated to start a software program.

  The software program management unit 25 manages the processes from the start to the end of a program such as an OS for operating the optical disc apparatus 1 recorded in the ROM layer 5 of the optical disc 2 and the storage unit 3, and other application programs. Thus, the operation by various programs is realized.

  Further, in the optical disc apparatus 1, when the interlayer movement flag is recorded in the identification information recording area 41 of the RE / R layer 4 as in the optical disc 2, the identification information reproduction instruction unit 221 uses the interlayer movement flag. When the identification information reproduction instruction unit 221 reproduces the interlayer movement flag set to “1”, the interlayer jump instruction unit 222 may perform the interlayer movement.

  As a result, it is possible to shorten the processing time from the acquisition of the identification information to the activation of the program recorded in the ROM layer using an optical information recording medium such as the optical disc 2 having the flag for interlayer movement.

  Further, in the optical disc apparatus 1, the recording control unit 26 generates and records the interlayer movement flag in the identification information recording area (the empty area) of the optical information recording medium in which the interlayer movement flag does not exist. Anyway.

  In this case, the identification information reproduction instruction unit 221 of the optical disc apparatus 1 reproduces the interlayer movement Flag recorded by the recording control unit 26 together with the identification information, and the identification information reproduction instruction unit 221 is set to “1”. When the interlayer movement flag is reproduced, the interlayer jump instruction unit 222 may perform interlayer movement.

  As a result, the optical disc apparatus 1 can create an optical information recording medium in which the interlayer movement flag is recorded in the identification information recording area from the optical information recording medium in which the interlayer movement flag is not recorded in the identification information recording area. Therefore, by using this optical information recording medium, it is possible to shorten the processing time from the acquisition of the identification information to the activation of the program recorded in the ROM layer.

  Note that the timing at which the recording control unit 26 generates the interlayer movement flag, etc., is an optical information recording medium in which no interlayer movement flag exists for the recording control unit 26 via the operation unit 7. It may be at the time when an instruction to generate and record an interlayer movement flag (interlayer movement permission information recording instruction) is given in the identification information recording area (an empty area), or the disk management unit 21 It may be a point in time when it is recognized that an optical information recording medium in which no moving flag is recorded is loaded. It should be noted that at the latter time point, the disk management unit 21 may instruct the recording control unit 26 to generate an inter-layer transfer flag.

  According to the above, in the RE layer or the R layer of the optical information recording medium (including the optical information recording medium other than the optical information recording medium including the flag for interlayer movement such as the optical disk 2 and the optical disks 2A to 2C described below). At the stage where the structure of the optical information recording medium can be specified by reading the identification information recorded in advance in the identification information recording area, a predetermined interlayer movement is performed, and the information recorded in the ROM layer is reproduced. After the identification information is acquired and the structure of the optical information recording medium can be specified, the light spot is moved to the ROM layer without moving to the same RE layer or R layer. The recorded information (for example, a program such as software) can be read.

  Thereby, it is possible to shorten the processing time from the acquisition of the identification information to the activation of the program recorded in the ROM layer.

[3. Operation of optical information recording / reproducing apparatus]
Next, the details of the operation of the optical disc apparatus 1 will be described with reference to FIGS. In addition, [3. The configuration other than that described in [Operation of optical information recording / reproducing apparatus] is described in [1. Configuration of optical information recording medium] and [2. Configuration of optical information recording / reproducing apparatus]. For convenience of explanation, [1. Configuration of optical information recording medium] and [2. Members having the same functions as those shown in the drawing of the configuration of the optical information recording / reproducing apparatus] are given the same reference numerals, and the description thereof is omitted. In the following items, the same description is omitted.

  First, the operation flow of FIG. 4A shows an operation flow when the ROM layer 5 starts from the inner periphery side of the optical disc 2 and is reproduced to the outer periphery side, and the operation flow of FIG. The operation flow when the ROM layer 5 starts from the outer peripheral side of the optical disc 2 and is reproduced toward the inner peripheral side is shown.

  Each of the operation flows in FIGS. 4A and 4B is determined by the spiral direction of the optical disc 2.

  In this operation flow, the case where the optical disk 2 is used will be described, and it is assumed that the interlayer movement flag is always set to “1” (that is, the description regarding the interlayer movement flag is omitted below). Further, the identification information recording area 41 of the RE / R layer 4 in which the flag for interlayer movement exists is present on the inner peripheral side of the optical disc 2, and the user recording area 43 is reproduced to the outer peripheral side by the inner peripheral start. Assumption.

  However, the scope of the present invention is not limited to the above embodiment. For example, in the case of an optical information recording medium without an inter-layer movement flag, as described above, the optical disk apparatus 1 can be configured to control inter-layer movement and the like by the operation on the optical disk apparatus 1 side. Further, after the optical information recording medium is configured to include the interlayer movement flag by the optical disc apparatus 1, the value described below may be set to “1” to perform the operation described below.

  Further, steps other than step S3 in FIG. 4A (hereinafter, “step” is omitted) and S13 in FIG. 4B are common to FIGS. 4A and 4B. The operation flow of FIG. 4 (a) will be mainly described, and only the operation flow of S13 will be described with respect to the operation flow of FIG. 4 (b).

  First, in the operation flow of FIG. 4A, when the optical disk 2 is loaded at a predetermined position in the optical disk apparatus 1 in S1, the disk loading recognition unit 6 detects the loading of the optical disk 2, and the detection signal ( A loading detection signal) is transmitted to the disk management unit 21 of the control unit 20, and the process proceeds to S2.

  In S <b> 2, the disc management unit 21 operates the identification information reproduction instructing unit 221 of the reproduction control unit 22, triggered by receiving a loading detection signal from the disc loading recognition unit 6.

  The identification information reproduction instruction unit 221 causes the pickup control unit 23 to operate the pickup drive circuit 13 to control the position of the optical pickup, and causes the laser control unit 24 to operate the laser drive circuit 14 to generate a reproduction laser (reproduction light). The control to irradiate the optical disc 2 is performed, the identification information recorded in the identification information recording area 41 of the optical disc 2 is reproduced, the fact is notified to the reproduction data processing unit 223 (identification information reproduction notification), and the process goes to S3. move on.

  In S3, the reproduction data processing unit 223 that has received the identification information reproduction notification stores the identification information reproduction data reproduced in S2 transmitted from the reproduction circuit 15 to the control unit 20, and stores the identification information reproduction data stored in the storage unit 3. The information is recorded in the unit 31 and the fact is notified to the disk management unit 21 (identification information acquisition notification).

  Upon receiving the identification information acquisition notification, the disc management unit 21 specifies the structure of the optical disc 2 based on the identification information recorded in the identification information reproduction data storage unit 31, and determines the layer structure according to the specified structure of the optical disc 2. The jump instruction unit 222 is operated.

  The interlayer jump instruction unit 222 causes the pickup control unit 23 to move the light spot of the reproduction laser of the optical pickup 12 from the current position (interlayer jump start position SP) to a predetermined interlayer jump end position EP, and proceeds to S4. .

  In the operation flow of FIG. 4A, it is assumed that the interlayer jump end position EP is determined on the inner peripheral side of the ROM layer 5 of the optical disc 2.

  As an example of such interlayer movement, the patterns of FIGS. 5, 7, and 9 can be considered.

  FIG. 5 shows a case where the optical disc 2 is moved between the inner layers of the ROM layer 5.

  FIG. 7 shows an optical disc 2A having two ROM layers similar to the ROM layer 5 of the optical disc 2 (the two ROM layers 5A and 5B are in front of the incident direction of the reproduction light). It shows the case of moving.

  FIG. 9 shows an optical disc 2C in which a RE / R layer similar to the RE / R layer 4 of the optical disc 2 is set in front of the incident direction of the reproduction light and two ROM layers 5A and 5B are provided in the back, and the ROM layer 5A The case of moving between layers is shown.

  When the interlayer jump end position EP is set on the inner circumference side of the optical disc 2, the optical disc 2A, and the optical disc 2C as in these patterns, the identification information recorded in the identification information recording area 41 is reproduced to reproduce the optical disc 2. After that, the distance for moving the light spot to the position (interlayer jump end position EP) on the information recording surface where the information is previously recorded in the ROM layer 5 (ROM layer 5A and ROM layer 5B) is shortened. Therefore, it is possible to shorten the processing time from the acquisition of the identification information to the activation of the program recorded in the ROM layer 5 (ROM layer 5A and ROM layer 5B).

  5, 7, and 9, all the movements are the shortest distance between the identification information recording area 41 of the RE / R layer 4 and the ROM layer 5 (moving directly above and below the paper surface). Yes.

  According to such interlayer movement, it is possible to minimize the processing time from the acquisition of the identification information to the activation of the program recorded in the ROM layer 5 (ROM layer 5A and ROM layer 5B).

  As an example of the “shortest distance”, when there is a single ROM layer as in the example of FIG. 5, a straight line passing through the interlayer jump start position SP and extending along the normal direction on the incident surface of the reproduction light, and the ROM The distance between the position of the intersection with the information recording surface of the ROM layer 5 and the interlayer jump start position SP when the position of the intersection with the information recording surface of the layer 5 is taken can be exemplified.

  Further, when there are two or more ROM layers, among the positions of the intersections with the information recording surfaces of a plurality of ROM layers (ROM layer 5A and ROM layer 5B) as shown in FIGS. The position of the intersection closest to the interlayer jump start position SP (in FIG. 7, on the ROM layer 5B, in FIG. 9, on the ROM layer 5A) can be exemplified.

  Next, in S4, the reproduction control unit 22 operates the pickup control unit 23 and the laser control unit 24 to trigger the completion of the interlayer movement by the interlayer jump instruction unit 222 in the ROM layer 5 of the optical disc 2. Information recorded in advance is reproduced, and the reproduction data processing unit 223 is notified (ROM reproduction notification).

  Upon receiving the ROM reproduction notification, the reproduction data processing unit 223 records the ROM reproduction data transmitted from the reproduction circuit 15 in the ROM reproduction data storage unit 32 or the software program storage unit 33, and notifies the software program management to that effect. The unit 25 is notified (ROM reproduction data storage notification), and the process proceeds to S5.

  In S5, the software program management unit 25 receives the ROM reproduction data storage notification, reads the ROM reproduction data recorded in the ROM reproduction data storage unit 32 or the software program storage unit 33, starts the read program, END ".

  Next, the operation flow of S13 in FIG. 4B will be described.

  In S13, the reproduction data processing unit 223 that has received the identification information reproduction notification stores the reproduction data of the identification information reproduced in S12 transmitted from the reproduction circuit 15 to the control unit 20, and stores the identification information reproduction data in the storage unit 3. The information is recorded in the unit 31 and the fact is notified to the disk management unit 21 (identification information acquisition notification).

  Upon receiving the identification information acquisition notification, the disc management unit 21 specifies the structure of the optical disc 2 based on the identification information recorded in the identification information reproduction data storage unit 31, and determines the layer structure according to the specified structure of the optical disc 2. The jump instruction unit 222 is operated.

  The interlayer jump instructing unit 222 causes the pickup control unit 23 to move the light spot of the reproduction laser of the optical pickup 12 from the current position (interlayer jump start position SP) to a predetermined interlayer jump end position EP, and proceeds to S14. .

  4B, it is assumed that the interlayer jump end position EP is determined on the outer peripheral side of the ROM layer 5 of the optical disc 2.

  As an example of such interlayer movement, the patterns of FIGS. 6 and 8 can be considered.

  FIG. 6 shows a case where the optical disk 2 is moved between the outer layers of the ROM layer 5.

  FIG. 8 shows a case where the ROM layer 5 of the optical disc 2 is moved to the ROM layer 5 with the optical disc 2B in which the RE / R layer 4 is exchanged in the back in the reproduction light incident direction.

  When the interlayer jump end position EP is set on the outer peripheral side of the optical disc 2 and the optical disc 2B as in these patterns, the identification information in the RE / R layer 4 is on the inner peripheral side of the optical disc 2 and the optical disc 2B. The premise is that the light spot is moved from the interlayer jump start position SP to the interlayer jump end position EP, and then the light spot starts from the outer peripheral side and moves to the inner peripheral side.

  Therefore, for example, after reproducing information recorded in advance in the ROM layer 5, when accessing the RE / R layer 4 starting on the inner circumference side, the distance for moving the light spot is shortened, so that the recording operation is quickly started. be able to.

[4. (Timing of interlayer movement)
Next, a preferred timing for interlayer movement will be described. Here, the optical disk 2 will be described as an example of an optical information recording medium.

  A preferable first timing of the interlayer movement is before the management information recorded in the management information recording area 42 is reproduced.

  Thus, since information recorded in advance in the ROM layer 5 is reproduced before the management information is reproduced, the identification information is acquired from the ROM layer 5 after the identification information is acquired rather than the case where the management information is reproduced. It is possible to shorten the processing time until the recorded program or the like is activated.

  A preferred second timing of interlayer movement is before information is recorded in the user recording area 43 of the RE / R layer 4.

  As a result, the information recorded in advance in the ROM layer 5 is reproduced before the information is recorded in the RE / R layer 4 (by the recording control unit 26). Therefore, after the identification information is obtained, the RE / R layer 4 Compared to the case where information is recorded in the memory, the processing time from the acquisition of the identification information to the activation of the program recorded in the ROM layer 5 can be shortened.

  As described above, according to the optical disc apparatus 1, it is possible to shorten the processing time from the acquisition of the identification information to the activation of the program recorded in the ROM layer of the optical information recording medium such as the optical disc 2 or the optical discs 2A to 2C. .

  In the above, when the flag for interlayer movement is set to “1”, it indicates that interlayer movement is permitted, and when it is set to “0”, interlayer movement is not permitted. This has been described as an example, but the present invention is not limited to this.

  If the information indicating that the interlayer movement is permitted and the information indicating that the interlayer movement is not permitted are set as different data, the same operation as described above can be performed.

(Embodiment 2)
Next, Embodiment 2 of the present invention will be described. In the first embodiment, as shown in FIG. 1, a flag for interlayer movement different from normal identification information is recorded in the identification information recording area 41 of the optical disc 2. The flag for interlayer movement indicates that the interlayer movement from the identification information recording area 41 included in the RE / R layer 4 at the light spot position of the reproduction light to the ROM layer 5 is permitted or not permitted. Information.

  The optical disc apparatus 1 recognizes the setting contents of the flag for interlayer movement and executes the interlayer movement. By doing so, the identification information recorded in the identification information recording area 41 is recorded in the ROM layer 5 in advance. The processing time until the activated program is started is shortened.

  On the other hand, in Embodiment 2 of the present invention, information indicating permission / non-permission of the interlayer movement is not recorded separately from the normal identification information in the identification information recording area of the optical disc.

  That is, according to the present embodiment, the optical disk device 1 is composed of information recording layers in advance from the identification information recorded in advance in the identification information recording area of the optical disk, and what recording characteristics each information recording layer has. By recognizing the structure such as whether or not it is present, when it is recognized that there is a ROM layer in addition to the RE / R layer where the light spot position of the reproduction light is currently located, the above interlayer movement is executed. For this reason, it is not necessary to separately record information different from normal identification information such as the above-mentioned interlayer movement Flag in the identification information recording area of the optical disc.

  Therefore, in this embodiment, it is not necessary to reproduce information different from normal identification information, and as a result, it is possible to advance the time for performing the above-described interlayer movement.

  Embodiment 2 of the present invention will be described below with reference to the drawings. FIG. 10A is a schematic diagram conceptually showing an optical disc 2D according to Embodiment 2 of the present invention. Hereinafter, the same parts as those of the first embodiment of the present invention are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 10A, the optical disc 2D of the present embodiment includes at least a RE / R layer (first information recording layer) 4D and a ROM layer (second information recording layer) 5D. Information in the information recording layer can be read out by reproduction light. In the optical disc 2D, there are only two information recording layers, the RE / R layer 4D and the ROM layer 5D. However, the information recording layer may be three or more layers. Further, the RE / R layer 4D may be either the RE layer or the R layer.

  In the following, the differences between the RE / R layer 4D of the present embodiment and the RE / R layer 4 of the first embodiment will be mainly described, and the ROM layer 5D of the present embodiment and the ROM layer 5 of the first embodiment will be described. Different points will be described.

  First, differences between the RE / R layer 4D of the present embodiment and the RE / R layer 4 of the first embodiment will be described.

  As shown in FIG. 10A, the RE / R layer 4D of the present embodiment includes an identification information recording area 41D and a user recording area 43D. In the identification information recording area 41D of the RE / R layer 4D, normal identification information is recorded in advance.

  That is, the identification information recording area 41D of the RE / R layer 4D according to the present embodiment is different from the identification information recording area 41 of the RE / R layer 4 according to the first embodiment, and is used for interlayer movement different from normal identification information. Flag is not recorded.

  In the optical disc 2D of the present embodiment, when the identification information is recorded in advance in the identification information recording area 41D of the RE / R layer 4D, the identification included in the RE / R layer 4D at the light spot position of the reproduction light. It is recognized that the interlayer movement from the information recording area 41D to the ROM layer 5D is permitted.

  As in the first embodiment, the identification information recorded in advance in the identification information recording area 41D includes the disc layer type, the disc size, the disc version, the standard conditions for recording / reproducing on the disc, the servo. Polarity, recording mark polarity and disc-specific number. Each of such various information is normally recorded repeatedly in the identification information recording area 41D.

  For this reason, for example, after reading of the identification information recorded in advance in the identification information recording area 41D is started, the optical disk apparatus 1 is set so as to perform a predetermined interlayer movement when the structure of the optical disk 2D can be specified. What is necessary is just to comprise.

  In this case, after the identification information is acquired and the structure of the optical disc 2D is specified, the optical spot is moved to the ROM layer 5D without being moved to the same RE / R layer 4D, and recorded on the ROM layer 5D. Information (for example, a program such as software) can be read.

  That is, since the above-described interlayer movement can be performed without reading all of the identification information recorded in advance in the identification information recording area 41D, a program recorded in the ROM layer 5D from the acquisition of the identification information can be obtained. It is possible to shorten the processing time until activation.

  Next, differences between the ROM layer 5D of the present embodiment and the ROM layer 5 of the first embodiment will be described.

  As shown in FIG. 10A, unlike the ROM layer 5 of the first embodiment, the ROM layer 5D of the present embodiment stores management information for managing information reproduction in the ROM layer 5D in advance. Management information recording area 51D.

  Of course, the management information recorded in advance in the management information recording area 51D does not have to be unique in the optical disc 2D. For example, the RE / R layer 4D includes a management information recording area (not shown). As a matter of course, the same management information may be recorded in the management information recording area. In short, it is only necessary that the ROM layer 5D includes a management information recording area 51D in which management information for managing reproduction of its own information is recorded in advance.

  Further, as shown in FIG. 10A, the management information recording area 51D of the ROM layer 5D is disposed directly below the paper surface of the identification information recording area 41D of the RE / R layer 4D. FIG. 10A shows a state where the spot position of the reproduction light from the optical pickup 12 is moved from the interlayer jump start position SP to the interlayer jump end position EP.

  Specifically, the interlayer jump start position SP is a position on the identification information recording area 41D when the structure of the optical disc 2D is specified from the identification information of the identification information recording area 41D. On the other hand, the interlayer jump end position EP is a position on the management information recording area 51D of the ROM layer 5D.

  Then, the interlayer movement from the identification information recording area 41D of the RE / R layer 4D to the management information recording area 51D of the ROM layer 5D is performed with the shortest distance.

  Therefore, the management information can be reproduced immediately after obtaining the identification information. For this reason, as compared with the case where the management information recorded in the management information recording area (not shown) of the RE / R layer 4D is reproduced, the process from the acquisition of the identification information to the activation of the program recorded in the ROM layer 5D Time can be shortened.

  The management information recording area 51D of the ROM layer 5D in FIG. 10A is arranged directly below the paper surface of the identification information recording area 41D of the RE / R layer 4D, but this embodiment is limited to this configuration. It is not a thing. For example, like the optical disk 2E shown in FIG. 10B, the management information recording area 51E of the ROM layer 5E is close to the identification information recording area 41E of the RE / R layer 4E along the radial direction of the optical disk 2E. It may be arranged.

  Even in this case, since the interlayer movement from the identification information recording area 41D of the RE / R layer 4D to the management information recording area 51D of the ROM layer 5D is performed at a relatively short distance, the management information is reproduced immediately after the identification information is acquired. be able to.

  FIG. 10A shows an example in which the interlayer jump end position EP is near the center of the management information recording area 51D of the ROM layer 5D. However, the present invention is not limited to this. It may be in the management information recording area 51D, or may be in the vicinity of the management information recording area 51D.

  FIG. 10B also shows an example in which the interlayer jump end position EP is near the center of the management information recording area 51E of the ROM layer 5E, but is not limited thereto. It may be in the management information recording area 51E, or may be in the vicinity of the management information recording area 51E.

(Embodiment 3)
Next, a third embodiment of the present invention will be described. In the first embodiment, as shown in FIG. 1, a flag for interlayer movement different from normal identification information is recorded in the identification information recording area 41 of the optical disc 2.

  On the other hand, Embodiment 3 of the present invention is an embodiment in which the flag for interlayer movement is not recorded in the identification information recording area 41 of the optical disc 2 but is recorded in the management information recording area 42 of the optical disc 2.

  Hereinafter, Embodiment 3 of the present invention will be described with reference to FIGS. Hereinafter, differences between the operation of the optical information reproducing apparatus in the present embodiment and the operation of the optical information reproducing apparatus in the first embodiment will be mainly described. Hereinafter, the same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  FIG. 11A is a flowchart showing the operation of the optical information recording / reproducing apparatus in the present embodiment, and FIG. 11B is a flowchart showing another operation of the optical information recording / reproducing apparatus in the present embodiment.

Further, in the operation flow of FIG. 11A, the interlayer jump end position EP is determined on the inner peripheral side of the ROM layer 5 of the optical disc 2. On the other hand, in the operation flow of FIG. 11B, the interlayer jump end position EP is determined on the outer peripheral side of the ROM layer 5 of the optical disc 2.

  In this operation flow, the case where the optical disk 2 is used will be described, and it is assumed that the interlayer movement flag is always set to “1” (that is, the description regarding the interlayer movement flag is omitted below). Further, the management information recording area 42 of the RE / R layer 4 where the flag for interlayer movement exists exists on the inner peripheral side of the optical disc 2, and the user recording area 43 is reproduced to the outer peripheral side by the inner peripheral start. Assumption.
