Typical optical discs include write-once CD-R discs, DVD-R discs, DVD + R discs, rewritable CD-RW discs, DVD-RW discs, DVD + RW discs, DVD-RAM discs, There are also read-only CD-ROM discs and DVD-ROM discs that are already widely used.

[0003] On the other hand, as a format standard of a recording medium, for example, regarding a CD system such as a CD-R disc and a CD-RW disc, Sony Corporation and Philips Corporation (both are registered trademarks) There is the Orange Book standard established at the center, and DVD-RAMZRZRW standard established mainly by the DVD Forum (Fom m) for DVD systems such as DVD-RAM disk, DVD-R disk, and DVD-RW disk. There is. In addition, there is a DVD + RW / + R standard established around DVD + alliance.

[0004] In the above-mentioned standard, when a CD is used to reproduce information recorded on an optical disc by, for example, a CD player or a CD-ROM drive, and in the case of a DVD, for example, a DVD-ROM drive or a DVD player is used. It is stipulated that necessary data (for example, information on the write area “session” specified by the format standard) is recorded.

[0005] Therefore, a versatile writing drive that supports an industry-standard information recording medium

In the (recording device), data is recorded in a prescribed “session”.

[0006] On the other hand, in a "session" specified by the format standard, a read-only area (recorded area) in which a computer program or the like is recorded in advance at the time of shipment, and a data after shipment. There is a hybrid disk (for example, CD-ROM) having an additional write area (unrecorded area) in which data can be written.

[0007] This hybrid disc (for example, a CD-ROM) can be duplicated by injection molding with a stamper using a master on which a large amount of software is stored, but is not suitable for supplying individual software. In spite of the problem, a proposal has been made to solve the problem by recording encryption information for individually licensing software in an additional writing area (unrecorded area) (for example, JP-A-6-349248). .

[0008] Also, some discs, such as hybrid discs, utilize a structure capable of newly forming pits in gnorebs, and enable rewriting of a read-only area (recorded area). is there.

As a format standard, there is an orange book standard for a CD system, and a DVD—RA MZRZRW standard and a DVD + standard established by a DVD forum (Forum) for a DVD system. There is the DVD + RW / + R standard established by the Alliance.

[0054] Among these standards, DVD-RAM discs, DVD-RW discs, and DVD + RW discs have a single session configuration for one session, and the other discs have multiple sessions for multiple discs. It has a session configuration and defines standards for recording in multiple sessions.

[0055] The above standard considers the case where information recorded on a CD or DVD is reproduced by an information reproducing apparatus for reproducing an optical disk, for example, a CD player, a CD-ROM drive, a DVD-ROM drive, or a DVD player. , A predefined session ("Industry standard optical It corresponds to a "writing area specified in a recording medium format standard defined for a general-purpose recording device for recording information on a disk." ) Is specified to record data. Therefore, when information is recorded on an optical disk by a general-purpose recording device (general-purpose writing drive), data is recorded in a specified session.

FIG. 3 is a diagram showing a format of the optical disc 30 shown in FIG.

FIG. 3A shows a single-session configuration in a DVD-RAM disk, a DVD-RW disk, and a DVD + RW disk.

[0058] A lead-in (Lead_In) area 40, a data (Data) area 41, and a lead-out (Lead-Out) area

One session constituted by the) area 42 corresponds to a “writing area”.

[0059] The area outside the write area specified by the recording medium format standard defined for the general-purpose recording apparatus according to the present invention, that is, the shaded area on the outer peripheral side of the lead-out area 42. Data or a program is recorded in advance in a shaded area 43 on the inner peripheral side of the lead-in area 43 or the lead-in area 40.

FIG. 3B shows a multi-session configuration of a CD-R disc, a CD-RW disc, a DVD-R disc, a DVD + R disc, and a DVD-RW disc.

As shown in FIG. 3B, the first session includes (lead-in area 1) 50, (data area 1) 51, and (lead-out area 1) 52. Further, the Nth session is composed of (Lead-in area N) 53, (Data area N) 54, and (Lead-out area N) 55.

As described above, N session areas from the first session to the N-th session correspond to the “writing area”.

Then, an area outside the write area specified by the recording medium format standard defined for the general-purpose recording apparatus according to the present invention, that is, the lead-out area 55 of the last session (Nth session) of the “write area” In the hatched area 56 on the outer peripheral side or the hatched area 57 on the inner peripheral side of the lead-in area 50 of the first session (first session) of the “writing area”. The data or the program is recorded in advance.

[0064] The recording of data or programs in the shaded areas 43, 44, 56, 57 may be performed by pre-stamping. That is, the optical disc 30 includes a recording medium having a data recordable area outside a write area specified by a recording medium format standard defined for a general-purpose recording apparatus according to the present invention, and a general-purpose recording medium. This corresponds to a recording medium that has an area in which data is formed by pre-stamp outside the write area specified by the recording medium format standard specified for the device.

Therefore, when the optical disk 30 is used in a general optical disk recording device (general-purpose recording device), the optical disk 30 refers only to the writing area specified by the recording medium format standard for the general-purpose recording device, and Data is recorded only in the writing area.

[0067] First, the program stored in the program storage unit 13 of the higher-level device 1 must be a recording medium having an area where data can be recorded outside the write area specified by the recording medium format standard for general-purpose recording devices. Is added and recorded.

[0068] More specifically, "SFF8090I

In the excerpt from the “VI.48 (Draft) standard”, there is a general table in the “128” profile list (Tablel28 Profile List) that is described in the item of 14.4 Get 'Configuration' Command (Get Configuration Command). Information indicating that the recording medium has a data recordable area outside the write area specified by the recording medium format standard for the recording device is additionally recorded.

[0069] Then, upon receiving a notification from the DVD + RW drive device 2 that the optical disk has been inserted, the host device 1 sends a get 'configuration' command to the DVD + RW drive device 2, and the DVD + RW drive device 2 When the optical disk 30 is inserted, the optical disk 30 detects that the optical disk 30 is mounted, and indicates that the optical disk 30 is mounted (data can be recorded outside a write area specified by a recording medium format standard for a general-purpose recording device). Information indicating that the recording medium has a special area).

[0070] Therefore, the higher-level device 1 has mounted on the DVD + RW drive device 2 an optical disk 30 having a data recordable area outside the write area specified by the recording medium format standard for a general-purpose recording apparatus. Can be recognized.

[0071] In addition, the DVD + RW drive device 2 is used for a general-purpose recording device in accordance with the read capacity command (Read Capacity Command) described in item 14.20 of the above-mentioned standard. A bit setting corresponding to a recording medium having a data recordable area outside the write area specified by the recording medium format standard is provided, and the host device 1 transfers the read capacity to the DVD + RW drive device 2. If the bit is set by sending the 'City' command, the DVD + RW drive unit 2 will use the general-purpose recording information of the optical disc 30 as information similar to the table 286 described in section 14.20 of the above standard. The logical block address and block length (block length) of the area where data can be recorded outside the write area specified by the recording medium format standard for the device are notified to the host device 1. Therefore, the host device 1 can recognize the position of an area where data can be recorded outside the write area of the optical disk 30 specified by the recording medium format standard for general-purpose recording devices.

[0072] Further, regarding the read command (Read Command) described in the section 14.16 of the above-mentioned standard and the write command described in the section 14.48, (Write Command), Area where the logical block address and block length (block length) are notified by the above read 'capacity' command (“Area where data can be recorded outside the write area specified by the recording medium format standard for general-purpose recording devices”) ) Is defined so that data can be read from and written to. Alternatively, new read and write commands for data reading and data writing may be defined and provided in the same format as before.

As described above, in the program stored in the program storage unit 13 of the higher-level device 1, the target area of the write command and the read command of the command specification for the DVD + RW drive device 2 is specified in the optical disk 30. It is defined in advance to extend to an area other than the session (corresponding to an area outside the write area specified by the recording medium format standard for general-purpose recording devices). Further, a new write command and a new read command for an area other than the session in which the target area is specified may be added.

[0074] Then, the host device 1 sends a read command and a write command to the DVD + RW drive device 2 so that the area other than the specified session on the optical disk 30 (specified by a recording medium format standard for general-purpose recording devices). It also instructs data writing and data reading to the area where data can be recorded outside the written area. Next, the processing of this information recording device will be described.

FIG. 4 is a flowchart showing processing of the information recording device shown in FIG.

As shown in FIG. 4, the CPU 10 of the higher-level device 1 performs the DVD (step S

It is determined whether or not an optical disk has been set in the + RW drive device, and if it is determined based on the notification from the DVD + RW drive device that the optical disk has been set, the `` Get 'Configuration' Command) to determine whether or not the optical disk has an area outside the write area specified by the recording medium format standard for general-purpose recording devices based on the notification from the DVD + RW drive device. If not, an operation corresponding to the type of the optical disk is executed in step 4.

If it is determined in step 2 that the optical disk has an area outside the write area specified by the recording medium format standard for a general-purpose recording apparatus, a “read capacity command” is sent to the DVD + RW drive. And information on the area outside the write area of the optical disk specified by the recording medium format standard for general-purpose recording devices based on the notification from the DVD + RW drive device, and the general-purpose recording device Refers to the area other than the write area of the optical disk specified by the recording medium format standard for data, acquires the data or program recorded in the referenced area, and executes the processing based on the data or program. DVD + RW drive unit Sends the created data together with the write command to write data for a general-purpose recording device. Record in the write area of the optical disk specified by the recording medium format standard, and return to step 1.

[0079] For example, additional information such as a template for storing images and background music is stored in the shaded area in FIG. 3 in advance, and the higher-level device 1 acquires the additional information, and stores the additional information. It creates and decorates multimedia contents such as still images, audio, and moving images based on the data, and specifies the data of the created multimedia contents in a recording medium format standard for general-purpose recording devices. Recorded on the write area of the optical disc 30.

Further, for example, a program is stored in advance in an area indicated by hatching in FIG. 3, and the higher level device 1 acquires the program, executes the program to create data, and Optical disk specified by the recording medium format standard for the recording device The data is recorded in the write area.

[0081] Further, for example, a key for a symbol is recorded in advance in an area indicated by hatching in FIG. 3, and data created by a higher-level device is recorded on the optical disk using the key. By doing so, you can also protect your data.

[0082] In this way, by using data in an area that cannot be accessed by the general-purpose reading device and writing device for the recording medium for recording in an area that can be accessed by the device, the data in the accessible area can be recorded.隠 Concealment such as “喑” is easily performed.

[0083] Further, since the concealment data cannot be read by a general-purpose reading device, the security can be improved. Since writing cannot be performed by a general-purpose writing device, even in the case of a rewritable medium, the concealment data cannot be read. Data recorded outside the area specified as the writing area may not be rewritten.

Further, by recording the additional information with a pre-stamp, even if the base (attribute) is a rewritable medium, the data recorded outside the area designated as the final write area can be stored in the claim. Even if the writing device of 1 is used, it will not be accidentally rewritten.

Next, in the program storage unit 13 of the information recording device, a reference procedure for referring to the management information recorded on the recording medium in the computer, and a writing area defined by the management information referred to by the reference procedure A reading procedure for reading data or a program recorded in an outer area, a processing procedure for processing data by using the data or a program read by the reading procedure, and data processed by the processing procedure. Is stored in the write area.

[0086] Then, by the CPU 10 executing the program, a reference step of referring to the management information recorded on the recording medium and an area outside the writing area defined by the management information referenced in the reference step are performed. A reading step of reading recorded data or a program, a processing step of processing data using the data or the program read in the reading step, and recording of data processed by the processing step in the write area. A recording method including a recording step is performed.

That is, the CPU 10 refers to the reference unit that refers to the management information recorded on the recording medium, and writes the reference information to an area outside the writing area defined by the management information referenced by the reference unit. Reading means for reading the recorded data or program, processing means for reading data using the data or program read by the reading means, and data processed by the processing means in the write area. Acts as a recording means for recording.

Further, it is assumed that the management information is information in which a storage capacity smaller than the maximum storage capacity that can be physically secured as the storage capacity of the writing area in the recording medium is defined as the storage capacity of the writing area. Good.

Alternatively, the management information may be information that defines an address smaller than the maximum address that can be physically secured as a write area in the recording medium as the maximum writable address of the write area.

Alternatively, an address smaller than the maximum address that can be physically specified as the start address of the area indicating the end of the write area in the recording medium is used as the management information.

The information may be defined as the maximum possible address of the start address of the area indicating the end.

[0091] The optical disc in this case is a recording medium on which information can be written, in which management information including a rule regarding a writing area is recorded, and an area outside the writing area specified in the management information. Is provided with a data or program storage area.

[0092] Further, the management information may be information in which a storage capacity smaller than the maximum storage capacity that can be physically secured as the storage capacity of the write area in the recording medium is defined as the storage capacity of the write area. Good.

[0093] Alternatively, the management information may be information that defines an address smaller than the maximum address that can be physically secured as a write area in the recording medium as the maximum possible address of the write area.

Alternatively, an address smaller than the maximum address that can be physically specified as the start address of the area indicating the end of the write area on the recording medium may be used as the start address of the area indicating the end. The information should be specified as the maximum possible address.

[0095] Furthermore, the data or program recording area of the optical disk is pre-written with data or Or record a program.

[0096] Alternatively, data or a program may be recorded in a recording area of the data or the program on the optical disc in advance with a pre-stamp.

[0097] Furthermore, information indicating that the recording medium has a recording area for data or a program outside the writing area may be recorded in the management information.

[0098] For example, in a DVD + R disc and a DVD + RW disc, there is a control data zone in the lead-in area 40 shown in FIG. The maximum address that can be secured as a write area is defined as a possible 'physical' sector (last possible physical sector).

[0099] Accordingly, the value of the last possible physical sector is used as the management information according to the present invention, and is smaller than the maximum storage capacity that can be physically secured as the storage capacity of the write area in the recording medium. The storage capacity is defined as the storage capacity of the above-mentioned writing area so that the storage capacity appears to be smaller than the actual physical capacity.
