Description

  The present invention relates to an optical recording disk, and more particularly to an optical recording disk that prevents the use of a general-purpose optical recording disk on which data on the optical recording disk is copied.

  Recently, optical recording disks that record program data used in personal computers, game software, video data, music data, and the like as optical data have become widespread.

General-purpose optical recording discs include read-only discs with pre-recorded data such as DVD-ROM (Digital Versatile Disc-Read Only Memory), writable discs such as DVD-R (DVD-Recordable), DVD Rewritable discs such as RW (DVD-ReWritable) and DVD-RAM (DVD-Random Access Memory) are in practical use.
Also, DVD + R and DVD + RW specifications with different application formats or DVD ± VR specifications have been put into practical use.

  Also, general-purpose optical recording discs with different recording formats have been developed, and single-sided single-layer recording type having a recording capacity of 4.7 GB (gigabyte) and single-sided dual-layer recording type having a recording capacity of 8.5 GB are practical. It has become.

  Also, unlike DVD, general-purpose light such as read-only CD-ROM (Compact Disc-Read Only Memory), writable CD-R (CD-Recordable), rewritable CD-RW (CD-ReWritable), etc. Recording disks have been put into practical use. CD-ROMs conforming to the music CD (CDDA: Compact Disc Digital Audio) standard are also provided.

Among such general-purpose optical recording disks, DVD-ROMs and CD-ROMs press a press master made on the basis of data onto a blank disk or burn data onto a writable general-purpose optical recording disk. By writing, the data is provided in a state in which data is stored in advance on the disk.
Moreover, general-purpose optical recording disks such as DVD ± R and CD-R, or DVD ± RW, CD-RW, and DVD-RAM can be written or rewritten on the user side using data recording software. .

Patent Document 1 discloses such an optical recording disk.
An optical recording disk records data from the inner periphery to the outer periphery of a disk by forming pits using a laser beam in a spiral high-density groove (groove) provided on the disk. It is possible to record a large amount of data on a small disk.
In particular, DVDs can record data that is six times larger than CDs and are becoming mainstream data storage.

  By the way, as described above, such a general-purpose optical recording disk can easily copy a large amount of data recorded on the disk to another general-purpose optical recording disk by using data recording software. . For this reason, various copy protection methods have been put into practical use for the purpose of copyright protection.

Examples of copy protection methods in practical use include the Macrovision method, Copy Generation Management System (CGMS), Contents Scrambling System (CSS), and Content Protection for Prerecorded Media ( CPPM), Content Protection for Recordable Media (CPRM), and Digital Transmission Content Protection (DTCP). In addition, a digital watermark (Digital WaterMark) method in which data specifying a copyright holder is embedded in stored data instead of performing direct copy protection has been put into practical use.
Japanese Patent Laid-Open No. 2003-054128

  However, the copy protection method described above is mainly applied to video discs and music discs, and a copy protection method suitable for optical recording discs on which data for personal computers and game software are recorded has not been put into practical use. It was.

  Further, since the copy protection method described above determines whether the disc is a copied disc on the deck or player side on which the disc is mounted, the discrimination processing depends on these devices, and normal discrimination is not possible. Often not done.

  Furthermore, all of the copy protection methods described above require special processing on the stored data, which increases the manufacturing cost and easily deteriorates the data along with the processing, and the provided data remains as it is. Since it was not stored on the disk, it was unsatisfactory for the data provider (copyright holder).

  The present invention has been proposed in view of the above circumstances, and provides an optical recording disk that can reliably prevent the use of a copied general-purpose optical recording disk without performing any processing on stored data. The purpose is to do.

In order to achieve the above object, the present inventors have taken the technical means described below.
The operating system (hereinafter referred to as OS) described in the following description refers to management of input / output data of peripheral devices including disk drives of devices such as personal computers, decks, players, etc. to which optical recording disks are mounted. , A basic program that performs memory management of the CPU (central processing unit) of the device, such as Windows (registered trademark or trademark of Microsoft Corporation in the United States and other countries), MS / DOS, or MacOS (United States and other countries) (Registered trademark of Apple Computer, Inc.).

  The file management system described below refers to a system formed on an optical recording disk by a logical format, and specifies a recording position (sector) of data (file) that is referenced by the OS and stored in the optical recording disk. Refers to the system.

  A first aspect of the present invention is an optical recording disk having a recording capacity expanded by a predetermined amount as compared with a general-purpose optical recording disk and storing data in advance, and performs predetermined processing when mounted on a disk drive. A startup file to be executed and a startup specification file for specifying automatic execution of the startup file are added to the data and stored, and the startup file is located at the end of the recording area prior to execution of a predetermined process. This is an optical recording disk having a function of performing access processing to activation confirmation data recorded in an enlarged recording area located.

When an optical recording disk of this aspect is installed in a disk drive such as a personal computer, a deck, or a player, the activation specification file is referred to by the OS that manages the disk drive, and the activation file specified in the activation specification file is automatically activated. The When the activation file is activated, an access process to the activation confirmation data recorded in the enlarged recording area is performed, and thereafter, a predetermined process such as menu display is performed by the activation file.
In other words, as long as the optical recording disk of this aspect is used, predetermined processing such as menu display is automatically executed, and the disk can be used.

  On the other hand, the optical recording disk of this aspect has a recording capacity increased by a predetermined amount compared to a general-purpose optical recording disk. Therefore, when copying the optical recording disk of this aspect to another general-purpose optical recording disk as it is using copy software, the startup confirmation data stored in the expanded recording area and the lead-out data added to the end It will not be recorded.

  However, the optical recording disk is recognized by the OS by reading the lead-in data and the lead-out data that are added and stored at the beginning and end of the data. In other words, even if any of the lead-in data and lead-out data is lost, the data session is not completed, so the disk is not recognized by the OS, and the disk cannot be used.

Therefore, when the copied general-purpose optical recording disk is mounted in the disk drive, since there is no lead-out data, the disk is not recognized by the OS, and the use of the disk is completely blocked.
In other words, if the optical recording disk of this aspect is directly copied to another general-purpose optical recording disk by using copy software, the copied disk becomes unusable.

  In addition, a file system that manages stored data by copying the optical recording disk of this aspect to another general-purpose optical recording disk while thinning out files and frames constituting the data using copy software The start specification file and start file are copied as they are. In addition, since the data is thinned out, the activation confirmation data and the lead-out data stored in the expanded recording area are recorded as they are.

However, the optical recording disk of this aspect has a recording capacity expanded by a predetermined amount as compared with a general-purpose optical recording disk. For this reason, the sector number assigned to the expanded recording area of the optical recording disk of this aspect does not exist in the general-purpose optical recording disk.
Therefore, in the copied general-purpose optical recording disk, there is no sector number indicating the sector in which the activation confirmation data managed by the file management system is recorded.

  For this reason, when a copied general-purpose optical recording disk is installed in the disk drive, the startup file is automatically started. However, when the startup confirmation data is accessed by processing the startup file, access to a nonexistent sector is performed. A system error occurs. As a result, subsequent processing of the startup file is stopped, and execution of predetermined processing such as menu display is prevented.

  In other words, even when copying the optical recording disk of this aspect so that it fits on a general-purpose optical recording disk while thinning out data using copy software, the copied disk is used without performing predetermined processing such as menu display. Be blocked.

Here, a case will be considered in which a single-recording type optical recording disk of this aspect is directly copied to a dual-layer recording type general-purpose optical recording disk having a recording capacity larger than that of the disk.
The two-layer recording general-purpose optical recording disk has the same recording capacity as the single-layer recording general-purpose optical recording disk, and the second-layer recording capacity is smaller than that of the first layer. Therefore, when a single-layer recording type optical recording disk is copied as it is to a dual-layer recording type general-purpose optical recording disk, the file management system, the start designation file, the start file and the data are copied as they are to the first layer recording area. . In addition, the activation confirmation data and the lead-out data stored in the expanded recording area protrude from the first layer and are directly copied to the second recording area.

  However, in a dual-layer recording type general-purpose optical recording disk, the first and second layers are managed separately by a file management system. For this reason, the sector number assigned to the expanded recording area of the single-layer recording type optical recording disk does not exist in the dual-layer recording type general-purpose optical recording disk. In other words, the copied dual-layer general-purpose optical recording disk does not have a sector number indicating the sector in which the activation confirmation data managed by the file management system is recorded.

  Therefore, when the copied general-purpose optical recording disk is installed in the disk drive, the startup file is automatically started, but when the startup confirmation data is accessed from the startup file, access to a nonexistent sector is performed. And a system error occurs. As a result, processing of the startup file is stopped, and execution of predetermined processing such as menu display is prevented.

  In other words, even if a single-layer recording type optical recording disc is copied as it is to a two-layer recording type general-purpose optical recording disc using copy software, the copied disc is used without performing predetermined processing such as menu display. Is blocked.

  As described above, according to this aspect, as long as the original optical recording disk is used, a predetermined process such as menu display is automatically executed and can be used. When copying on a layer-recording general-purpose optical recording disk, the copied disk is not subjected to predetermined processing such as menu display, and can be prevented from being used.

  Further, the optical recording disk of this aspect has a configuration in which the activation designation file, the activation file, and the activation confirmation data are only added to the data and stored, and it is not necessary to perform special processing on the stored data. As a result, the cost can be reduced and the data does not deteriorate with processing. Moreover, it is preferable for a data provider from the viewpoint that data is not processed.

  Further, according to this aspect, it is possible to prevent the use of a disk that has been copied by utilizing the lack of sectors accompanying copying. This makes it possible to reliably prevent the use of the copied disk without depending on the deck or player on which the disk is mounted.

  This aspect can be suitably employed for an optical recording disk that stores a PC software program that starts installation by processing a startup file, for example. Moreover, it can be suitably used for a disc having a function of displaying a chapter selection menu, a language designation menu, etc. by a startup file among game discs, video discs, music discs, and the like.

  In this aspect, as means for expanding the recording capacity by a predetermined amount as compared with the general-purpose optical recording disk, it is possible to adopt a configuration in which the track density of the physical format applied to the optical recording disk is increased.

  In addition, as a method for producing an optical recording disk of this aspect, a method of pressing a press master prepared beforehand based on recording data onto a blank disk can be adopted, which is suitable for mass production. It is also possible to employ a method of printing record data on a writable optical recording disk.

  Preferably, the activation file and the activation designation file are stored at the beginning of the recording area.

The data reading head built in the disk drive is located in the vicinity of the head side of the recording area of the optical recording disk when not accessed.
According to this preferable aspect, when the optical recording disk is mounted on the disk drive, the data reading head can be moved in a short time to the recording area located on the head side where the activation designation file and the activation file are stored. As a result, it is possible to start up the startup file in a short time and launch a predetermined process such as menu display.

  A second aspect of the present invention is an optical recording disk having a recording capacity expanded by a predetermined amount as compared with a general-purpose optical recording disk and storing data in advance. A startup file to be executed and a startup specification file for specifying automatic execution of the startup file are added to the data and stored, and a part or all of at least one of the startup file and the startup specification file Is an optical recording disk which is stored while being positioned in an enlarged recording area located on the end side of the recording area.

According to this aspect, when the optical recording disk is mounted on a disk drive such as a personal computer, a deck, or a player, the activation designation file is referred to by the OS, and the activation file designated by the activation designation file is automatically activated. Then, predetermined processing such as menu display necessary for reproduction of data recorded on the optical recording disk by processing of the startup file is executed.
In other words, as long as the optical recording disk of this aspect is used, predetermined processing such as menu display is automatically executed, and the disk can be used.

  However, the recording capacity of the optical recording disk of this aspect is increased by a predetermined amount compared to the general-purpose optical recording disk. For this reason, when copying the optical recording disk of this aspect to another general-purpose optical recording disk as it is using copy software, it is added to the start specification file or start file stored in the expanded recording area and the end of the data. The recorded lead-out data protrudes and is not recorded.

Therefore, when a copied general-purpose optical recording disk is mounted on a disk drive, the disk is not recognized because lead-out data does not exist, and the use of the disk is blocked.
In other words, if the optical recording disk of this aspect is directly copied to another general-purpose optical recording disk by using copy software, the copied disk cannot be used.

  In addition, when copying the optical recording disk of this aspect to fit on another general-purpose optical recording disk while thinning out the files and frames that make up the data using copy software, the file management system that manages the data remains unchanged Duplicated. Further, since the data is thinned out, the activation designation file or the activation file and the lead-out data stored in the expanded recording area are recorded as they are.

However, the optical recording disk of this aspect has a recording capacity expanded by a predetermined amount as compared with a general-purpose optical recording disk. For this reason, the sector number assigned to the expanded recording area of the optical recording disk of this aspect does not exist in the general-purpose optical recording disk.
In other words, in the copied general-purpose optical recording disk, there is no sector number indicating the activation designation file managed by the file management system or the sector where the activation file is recorded.

  Therefore, when a copied general-purpose optical recording disk is loaded into a disk drive, a non-existent sector is accessed at the time when the activation designation file or the activation file is executed, and a system error occurs. As a result, execution of the activation specification file and the activation file is prevented.

  In other words, even if data is thinned and copied so that the optical recording disk of this aspect fits on another general-purpose optical recording disk using copy software, the menu display on the copied disk is not performed and the processing is not performed. Be blocked.

Here, consider a case where data on an optical recording disk of this aspect of a single-recording type is copied as it is onto a dual-layer recording type general-purpose optical recording disk having a recording capacity larger than that of the disk.
As described above, the general-purpose optical recording disk of the double-layer recording type has the same recording capacity as that of the general-purpose optical recording disk of the single-recording type, and the recording capacity of the second layer is smaller than that of the first layer. Therefore, when a single-layer recording type optical recording disk is copied as it is to a two-layer recording type general-purpose optical recording disk, the file management system for managing data and the data are copied as they are to the first recording area. Also, the activation designation file or the activation file and the lead-out data protrude from the first layer and are copied as they are into the recording area of the second layer.

However, as described above, in the dual-layer recording type general-purpose optical recording disk, the first and second layers are managed separately by the file management system. For this reason, the sector number assigned to the expanded recording area of the single-layer recording type optical recording disk does not exist in the dual-layer recording type general-purpose optical recording disk.
That is, in the copied dual-layer recording type general-purpose optical recording disk, there is no sector number indicating the activation designation file managed by the file management system or the sector where the activation file is recorded.

  Therefore, when a copied general-purpose optical recording disk is loaded in the disk drive, a sector that does not exist is accessed when the activation designation file or activation file is executed, and a system error occurs. As a result, execution of the activation specification file and the activation file is prevented.

  In other words, even if you copy a single-layer recording type optical recording disk to a two-layer recording type general-purpose optical recording disk as it is using copy software, it is used without performing predetermined processing such as menu display on the copied disk. Is blocked.

  As described above, according to this aspect, as long as the original optical recording disk is used, a predetermined process such as menu display is automatically executed and can be used. When copying on a layer-recording general-purpose optical recording disk, the copied disk is not subjected to predetermined processing such as menu display, and can be prevented from being used.

  In addition, the optical recording disk of this aspect has a configuration in which the activation designation file, the activation file, and the activation confirmation data are only added to the data to be recorded and stored, and special processing is performed on the data to be stored. There is no need to apply. As a result, similar to the first aspect and the preferred aspect described above, cost savings can be achieved and data deterioration associated with processing does not occur. Moreover, it is preferable for a data provider from the viewpoint that data is not processed.

  Further, according to this aspect, it is possible to prevent the use of a disk that has been copied by utilizing the lack of sectors accompanying copying. As a result, similarly to the first aspect described above, it is possible to reliably prevent the use of the copied disc regardless of the deck or player on which the disc is mounted.

  Further, in the same manner as the first aspect described above, this aspect is an optical recording disk for a personal computer provided with a start-up file, or a game disc provided with a function for displaying a chapter selection menu, a language designation menu, etc. according to the start-up file. It can be suitably used for video discs, music discs, and the like.

  In this aspect, it is possible to adopt a configuration in which a part or all of either the activation designation file or the activation file is stored in the enlarged recording area. It is also possible to adopt a configuration in which a part or all of both the activation designation file and the activation file are stored in an enlarged recording area.

In this aspect, as a means for expanding the recording capacity by a predetermined amount as compared with the general-purpose optical recording disk, the track density of the physical format applied to the optical recording disk is set as in the first aspect of the optical recording disk. An increasing configuration can be adopted.
In addition, the method for producing the optical recording disk of this aspect adopts a method of using a press original plate or a method of burning recording data on a writable optical recording disk, as in the case of the optical recording disk of the first aspect. Is possible.

  According to a third aspect of the present invention, there is provided an optical recording disk having a recording capacity expanded by a predetermined amount as compared with a general-purpose optical recording disk and pre-stored data, wherein the read-out data is added to the data. Is an optical recording disk in which a part or all of the recording medium is stored in an enlarged recording area located on the end side of the recording area.

  As described above, the optical recording disk is not recognized by the OS because the data session is not completed even if any of the lead-in data and the lead-out data stored in addition to the data is lost. The disk cannot be used.

However, the optical recording disk of this aspect has a recording capacity expanded by a predetermined amount as compared with a general-purpose optical recording disk, and a part or all of the lead-out data is recorded in the expanded recording area. .
For this reason, if the optical recording disk of this aspect is copied as it is to another general-purpose optical recording disk using copy software, part or all of the lead-out data protrudes and is not recorded.

  Therefore, even if the copied optical recording disk is mounted in the disk drive, the data session is not completed because the lead-out data does not exist or is incomplete, and the disk is not recognized by the OS. This makes it possible to prevent use of the copied disk.

  Here, some video discs and music discs do not have a start designation file or start file, and the start processing is automatically started by the deck or player side on which the disc is mounted. Since such a disk does not include the activation designation file and the activation file, it is not possible to apply the configurations such as the first aspect described above, its preferable aspect, and the second aspect described above.

  However, this type of optical recording disk, even if it is a video disk or music disk that does not have an activation specification file or an activation file, simply stores the lead-out data in the expanded recording area. The use can be effectively prevented.

In this aspect, as a means for expanding the recording capacity by a predetermined amount as compared with the general-purpose optical recording disk, a configuration for increasing the track density of the physical format applied to the optical recording disk as in the first aspect described above. Can be taken.
In addition, the method for manufacturing the optical recording disk of this aspect can adopt a method using a press original plate or a method of printing recording data on a writable optical recording disk, as in the first aspect. .

  Preferably, the expansion value of the recording capacity is less than 5% of the recording capacity of the general-purpose optical recording disk.

  Here, the amount of expansion of the recording capacity can be set as appropriate. In other words, even if the expansion amount of the recording capacity is small, if the start confirmation data, the start specification file, the start file, or a part of the lead-out data can be recorded in the enlargement area, the copied separate data The general-purpose optical recording disk can be prevented from being used.

On the other hand, when the amount of expansion of the recording capacity increases, the track density of the physical format applied to the optical recording disk increases, and it becomes difficult to maintain the writing and reading compatibility with the general-purpose optical recording disk.
From the standpoint of maintaining the writing and reading compatibility of the general-purpose optical recording disk, the amount of expansion of the recording capacity is preferably less than 5% of the recording capacity of the general-purpose optical recording disk, and about 3% is optimal.

  A single-recording optical recording disk is preferable.

  As described above, even if the optical recording disk of this preferable aspect is copied as it is to a dual-layer general-purpose optical recording disk, the copied disk is not used because predetermined processing such as menu display is not performed.

  A DVD (Digital Versatile Disc) or a CD (Compact Disc) is preferable.

  According to this preferred aspect of the optical recording disk, by providing it as a DVD-ROM on which data has been recorded in advance, the data recorded on the disk can be copied to a general-purpose DVD ± R, ± RW, RAM and used. Can be effectively prevented.

  Further, according to this preferred aspect of the optical recording disk, by providing it as a CD-ROM in which data is recorded in advance, the data recorded on the disk is copied and used on a general-purpose CD-R, RW. This can be effectively prevented. The present invention can also be applied to a CD-ROM conforming to the music CD (CDDA) standard.

  According to the present invention, the copied general-purpose light is not subjected to any processing on the stored data, and is not dependent on the processing function of the device such as the personal computer, the deck, or the player on which the disc is mounted. It is possible to provide an optical recording disk that can reliably prevent use of the recording disk and can effectively protect the copyright.

  Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
The optical recording disk (DVD-ROM) 1 of the present embodiment is a single-recording type, and is approximately 3.2% compared to the 4.7 gigabyte (GB) recording capacity of a general-purpose optical recording disk (general-purpose DVD-ROM). The recording capacity is increased by (0.15 GB) and has a recording capacity of 4.85 GB.

In other words, as shown in FIG. 1, the optical recording disk 1 has an enlarged recording of 0.15 GB on the end side (outer peripheral side) of the 4.7 GB standard recording area 14 having the same capacity as the single-recording general-purpose optical recording disk. A recording area 10 of 4.85 GB to which an area (enlarged recording area) 15 is continuously added is provided.
In this embodiment, by increasing the track density of the physical format applied to the optical recording disk 1, a recording capacity of 4.85 GB, which is larger than the recording capacity (4.7 GB) of the general-purpose optical recording disk, is obtained.

  As in the general-purpose optical recording disk, the optical recording disk 1 has a recording film layer 1a formed in a region surrounded by a circle 11 having a radius of 22.6 mm from the center of the disk and a circle 12 having a radius of 58 mm from the center as shown in FIG. The recording area 10 has a recording capacity of 4.85 GB.

The optical recording disk 1 of the present embodiment is a DVD-ROM in which data is recorded in advance, and data shown in FIGS.
That is, in the standard recording area 14, lead-in data 16 is recorded in an area surrounded by an inner circle 11 and a circle 13 having a radius of 24 mm.

In the area following the lead-in data 16, a file management system 17 for performing disk management, an activation designation file 18, an activation file 19 and data 20 are recorded in order. Further, activation confirmation data 21 and lead-out data 22 are recorded in the enlarged recording area 15 following the standard recording area 14.
Here, the area where the activation confirmation data 21 is recorded is the recording area of the nth sector located at the head of the enlarged recording area 15.

  The lead-in data is control data for controlling writing and reading of the optical recording disk 1, and information on physical format, disk size, maximum transfer rate, number of disk layers, track path direction, full ROM or partial ROM. It is composed of data including information, recording linear density, track density, start sector value, and end sector value.

The file management system 17 refers to a file on the disk 1 by an OS that manages a disk drive (not shown) on which the optical recording disk 1 is mounted.
The file management system 17 includes a FAT (File Allocation Table) 17a or VAT (Virtual Allocation Table) 17a indicating a sector address in which data (file) is recorded, a file name, a directory name, an extension, a file size, and an entry address. And directory data 17b in which the data is stored.

  The activation designation file 18 is a file for designating a file to be automatically executed when the optical recording disk 1 is loaded in the disk drive. In this embodiment, a text file format “Autorun.inf” is used as the activation designation file 18, and the activation file 19 is designated as an automatic execution file by the file 18.

  The activation file 19 refers to the activation confirmation data 21 recorded in the nth sector which is the enlarged recording area 15 at the time of activation, and thereafter performs predetermined processing such as installation of recorded data and menu display for reproduction. It is a file. In the present embodiment, the execution file format “Autorun.exe” is used as the startup file 19.

  The lead-out data 22 is data including session end data indicating the end of the recording data.

  In other words, in the optical recording disk 1 of this embodiment, the lead-in data 16, the file management system 17, the activation designation file 18, the activation file 19 and the data 20 are recorded in order in the standard recording area 14 of the recording area 10. At the same time, it is a read-only disc in which the activation confirmation data 21 and the lead-out data 22 are recorded in the enlarged recording area 15.

In the present embodiment, the optical recording disk 1 is manufactured by pressing a pre-pressed original plate prepared in advance on the basis of data onto a blank disk.
The optical recording disk 1 can be manufactured by recording data on a DVD-R or the like having a 4.85 GB physical format and a logical format without using a press master.

Next, the operation when the optical recording disk 1 of the present embodiment is mounted in a disk drive (not shown) will be described with reference to FIGS.
When the optical recording disk 1 is loaded in the disk drive, the OS refers to the activation designation file 18 by the file management system 17 and activates the activation file “Autorun.exe” 19 designated as the automatic execution file.

When the activation file 19 is activated, the activation confirmation data 21 recorded in the nth sector of the enlarged recording area 15 is referred to by the process.
Thereafter, predetermined processing such as menu display necessary for installation and reproduction of data recorded on the optical recording disk 1 by processing of the activation file 19 is performed.

  In other words, as long as the original optical recording disk 1 is used, the activation file 19 is automatically activated to perform necessary display such as menu display, and the optical recording disk 1 can be used according to the menu.

  Next, a case where the optical recording disk 1 of the present embodiment is copied to a single-recording general-purpose optical recording disk (DVD-R) 5 using copy software will be described.

  First, using copy software, the data 20 recorded on the optical recording disk 1 in FIG. 2 is thinned out, and copied so that it can be accommodated in the single-recording general-purpose optical recording disk 5 having a recording capacity of 4.7 GB in FIG. The case will be described.

Of the files or frames forming the data 20, the number of files or frames to be thinned is specified and the data 20 is copied while being thinned. Then, as shown in FIG. 3, the lead-in data 16, the file management system 17, and the activation designation file 18 are copied as they are, and the thinned data 20 a is stored in the 4.7 GB general-purpose optical recording disk 5. The Further, the activation confirmation data 21 and the lead-out data 22 are copied as they are at the end of the thinned data 20a.
Therefore, the activation confirmation data 21 is recorded from the recording area of the (na) sector of the general-purpose optical recording disk 5 as the recording capacity of the thinned data 20a is reduced.

Here, since the recording capacity of the optical recording disk 1 of FIG. 2 is larger than that of the general-purpose optical recording disk 5 of FIG. 3, the nth sector and the subsequent sectors allocated to the expanded recording area 15 of the optical recording disk 1 are used. No sector number exists in the general-purpose optical recording disk 5.
That is, in the copied general-purpose optical recording disk 5, the sector number (nth sector) indicating the recording area of the activation confirmation data 21 managed by the file management system 17 is a sector number that does not exist.

  For this reason, even if the copied general-purpose optical recording disk 5 is installed in the disk drive and the activation file 19 is automatically activated, the activation confirmation data 21 is not accessed when the activation confirmation data 21 is accessed by the processing of the activation file 19. Access to the n sector is performed and a system error occurs. As a result, the processing of the startup file 19 is stopped, the predetermined processing such as menu display is not executed, and the use of the copied disk 5 is prevented.

  Next, the case where the optical recording disk 1 shown in FIG. 2 is directly copied to the general-purpose optical recording disk 5 having a recording capacity of 4.7 GB shown in FIG. 4 using copy software will be described.

  As described above, the optical recording disk 1 of the present embodiment shown in FIG. 2 has a recording capacity increased by 0.15 GB compared to the single-recording general-purpose optical recording disk of FIG. Therefore, when the optical recording disk 1 of FIG. 2 is copied as it is onto the single-recording general-purpose optical recording disk 5 of FIG. 4 using copy software, the activation confirmation data 21 stored in the enlarged recording area 15 and the lead-out are read out. Data 22 protrudes and is not recorded.

  However, in the optical recording disk, even if any of the lead-in data 16 and the lead-out data 22 is lost, the data session is not completed. Therefore, the disk is not recognized by the OS, and the disk cannot be used.

  Therefore, when the copied general-purpose optical recording disk 5 of FIG. 4 is installed in the disk drive, the lead-out data 22 does not exist, so the disk is not recognized by the OS, and the use of the disk is completely blocked.

  Next, the case where the optical recording disk 1 shown in FIG. 2 is copied as it is onto the dual-layer recording type general-purpose optical recording disk 6 having a recording capacity of 8.5 GB shown in FIG.

  Here, the recording capacity of the first-layer general-purpose optical recording disk 6 is 4.7 GB, which is the same as that of the first-layer recording-type general-purpose optical recording disk 5, and the recording capacity of the second-layer 6b is the first layer. Less than 3.8 GB.

  Therefore, when the optical recording disk 1 in FIG. 2 is copied as it is to the dual-layer general-purpose optical recording disk 6 shown in FIG. 5, the lead-in data 16, the file management system 17, and the activation designation file 18 are included in the first layer 6a. The activation file 19 and the data 20 are recorded as they are, and the activation confirmation data 21 and the lead-out data 22 protruding from the first layer 6a are recorded as they are in the second layer 6b.

However, in the two-layer recording type general-purpose optical recording disk 6 shown in FIG. 5, the management of the recording area by the file management system 17 is performed separately for the first layer and the second layer. Therefore, the activation confirmation data 21 is recorded from the 0 sector of the second layer. Therefore, in the optical recording disk 1 of FIG. 2, the nth sector in which the activation confirmation data 21 is recorded does not exist in the dual-layer recording type general-purpose optical recording disk 6 of FIG.
That is, in the copied general-purpose optical recording disk 6, the sector number (nth sector) indicating the recording area of the activation confirmation data 21 managed by the file management system 17 is a sector number that does not exist.

  Therefore, when the copied general-purpose optical recording disk 6 shown in FIG. 5 is installed in the disk drive, the activation file 19 is automatically activated, but does not exist when the activation file 19 is accessed from the activation file 19. Access to the nth sector is performed, and a system error occurs. As a result, processing of the startup file is stopped, and execution of predetermined processing such as menu display is prevented.

  As described above, according to the optical recording disk 1 of the present embodiment, as long as the original optical recording disk 1 is used as it is, predetermined processing such as menu display is automatically executed and can be used. However, when the original optical recording disk 1 is copied to the single-layer recording or double-layer recording general-purpose optical recording disks 5 and 6, predetermined processing such as menu display is not performed, and the use can be prevented.

  In addition, the optical recording disk 1 of the present embodiment has a configuration in which the activation designation file 18, the activation file 19, and the activation confirmation data 21 are added to the data 20 and stored, and the data 20 needs to be specially processed. Absent. As a result, cost savings can be achieved and data deterioration associated with processing does not occur. Moreover, it is preferable for the data provider from the viewpoint that the data 20 is not processed.

  Further, according to the present embodiment, it is possible to reliably prevent the use of the copied disc without depending on the deck on which the disc is mounted or the processing on the player side.

  In the present embodiment, the activation designation file 18 and the activation file 19 are recorded on the head side of the recording area 10, but these files may be recorded in appropriate portions of the recording area 10. Is possible.

(Second Embodiment)
Next, an optical recording disk 2 according to a second embodiment of the present invention will be described.

  The optical recording disk 2 of the present embodiment has a configuration in which the processing function and recording site of the stored file are changed in the optical recording disk 1 of the first embodiment. Accordingly, the same components are denoted by the same reference numerals, and redundant description is omitted.

  The optical recording disk (DVD-ROM) 2 of the present embodiment is a disk having the same 4.85 GB recording capacity as the optical recording disk 1 described in the first embodiment, and increases the track density of the physical format. Thus, a recording capacity larger than the recording capacity (4.7 GB) of the general-purpose optical recording disk is secured.

The optical recording disk 2 of this embodiment is a DVD-ROM in which data is recorded in advance, and data shown in FIGS. 6 and 7 is recorded.
That is, in the standard recording area 14, lead-in data 16, file management system 17, activation designation file 18 and data 20 are recorded in order. Further, an activation file 19 ′ and lead-out data 22 are recorded in the enlarged recording area 15 subsequent to the standard recording area 14.
Here, the area where the activation file 19 ′ is recorded is the nth sector located at the beginning of the enlarged recording area 15.

  The lead-in data 16, the file management system 17, the activation designation file 18, the data 20, and the lead-out data 22 are the same data as the optical recording disk 1 described in the first embodiment.

The startup file 19 ′ is a file that performs only predetermined processing such as installation of the recorded data 20 and menu display for playback. The startup file 19 ′ is transferred from the startup file 19 described in the first embodiment to the startup confirmation data 21. The access processing function is removed.
In the present embodiment, the execution file format “Autorun.exe” is used as the startup file 19 ′.

  The optical recording disk 2 of the present embodiment is manufactured by pressing a pre-pressed original plate prepared in advance on the basis of stored data onto a blank disk. The optical recording disk 1 can be manufactured by recording data on a DVD-R or the like having a 4.85 GB physical format and a logical format without using a press master.

Next, the operation when the optical recording disk 2 of the present embodiment is mounted in a disk drive (not shown) will be described with reference to FIGS.
When the optical recording disk 2 is loaded in the disk drive, the OS refers to the activation designation file 18 by the file management system 17 and activates the activation file 19 ′ designated as the automatic execution file.

When the activation file 19 ′ is activated, processing such as menu display necessary for installation and reproduction of data recorded on the optical recording disk 2 is performed.
In other words, as long as the original optical recording disk 2 is used, the activation file 19 ′ is activated and necessary display such as menu display is performed, and the optical recording disk 2 can be used according to the menu.

  Next, a case where the optical recording disk 2 of this embodiment is copied to a single-recording general-purpose optical recording disk (DVD-R) 5 using copy software will be described.

  First, using copy software, the data 20 recorded on the optical recording disk 2 shown in FIG. 7 is thinned out so that it can be accommodated in the single-recording general-purpose optical recording disk 5 having a recording capacity of 4.7 GB shown in FIG. The case of copying to will be described.

Of the files or frames constituting the data 20, the number of files or frames to be thinned is specified and the data 20 is copied while being thinned. Then, as shown in FIG. 8, the lead-in data 16, the file management system 17, and the activation designation file 18 are copied as they are and the thinned data 20 a is stored in the 4.7 GB general-purpose optical recording disk 5. The Further, the activation file 19 'and the lead-out data 22 are copied as they are at the end of the thinned data 20a.
Therefore, the activation file 19 is recorded from the recording area of the (na) sector of the general-purpose optical recording disk 5 by reducing the recording capacity of the thinned data 20a.

  Here, since the optical recording disk 1 in FIG. 7 has a larger recording capacity than the general-purpose optical recording disk 5 in FIG. 8, the sector numbers after the nth sector assigned to the expanded recording area are as follows. The general-purpose optical recording disk 5 does not exist.

  For this reason, when the copied general-purpose optical recording disk 5 is loaded into the disk drive, the non-existent nth sector is accessed when the activation file 19 'is activated by the activation designation file 18, resulting in a system error. Occurs. As a result, the processing of the startup file 19 is stopped, the predetermined processing such as menu display is not executed, and the use of the copied disk 5 is prevented.

  Next, a case where the data 20 recorded on the optical recording disk 2 shown in FIG. 2 is copied to the general-purpose optical recording disk 5 having a recording capacity of 4.7 GB shown in FIG. 9 by using copy software will be described. .

  As described above, the optical recording disk 2 of this embodiment shown in FIG. 7 has a recording capacity increased by 0.15 GB compared to the single-recording general-purpose optical recording disk of FIG. Therefore, when the optical recording disk 2 of FIG. 7 is copied as it is onto the single-recording general-purpose optical recording disk 5 of FIG. 9 using copy software, the startup file 19 and lead-out data stored in the enlarged recording area 15 are copied. 22 protrudes and is not recorded.

  However, as described above, in the optical recording disc, the data session is not completed even if any of the lead-in data 16 and the lead-out data 22 is lost. Is possible.

  Therefore, when the copied general-purpose optical recording disk 5 of FIG. 4 is installed in the disk drive, the lead-out data 22 does not exist, so the disk is not recognized by the OS, and the use of the disk 5 is completely blocked.

  Next, using the copy software, the data 20 recorded on the optical recording disk 2 shown in FIG. 7 is copied as it is to the general-purpose optical recording disk 6 of the double-layer recording type having the recording capacity of 8.5 GB shown in FIG. The case will be described.

  As described above, the recording capacity of the first-layer general-purpose optical recording disk 6 is 4.7 GB, which is the same as that of the first-layer recording-type general-purpose optical recording disk 5, and the recording capacity of the second-layer recording medium 6b is It is 3.8 GB less than the first layer.

  Accordingly, when the optical recording disk 1 of FIG. 7 is copied as it is onto the dual-layer general-purpose optical recording disk 6 shown in FIG. 10, the lead-in data 16, the file management system 17, and the activation designation file 18 are included in the first layer 6a. The start file 19 and the data 20 are recorded as they are. In the second layer 6b, the start-up file 19 'and the lead-out data 22 that protrude from the first layer 6a are recorded.

However, as described above, in the dual-layer general-purpose optical recording disk 6 shown in FIG. 10, the management of the recording area by the file management system 17 is performed separately for the first layer and the second layer. Accordingly, the activation file 19 ′ is recorded from the 0th sector of the second layer. For this reason, in the optical recording disk 2 of the present embodiment in FIG. 7, the nth sector in which the activation file 19 ′ is recorded does not exist in the dual-layer general-purpose optical recording disk 6 in FIG.
In other words, in the copied general-purpose optical recording disk 6, there is no sector number (nth sector) indicating the recorded sector of the activation file 19 ′ managed by the file management system 17.

  Therefore, when the copied general-purpose optical recording disk 6 shown in FIG. 10 is mounted in the disk drive, the n-th sector that does not exist is accessed when the activation file 19 is activated by the activation designation file 18, resulting in a system error. Occurs. As a result, the activation file is not activated, and execution of predetermined processing such as menu display is prevented.

  As described above, according to the optical recording disk 2 of the present embodiment, as long as the original optical recording disk 2 is used as it is, predetermined processing such as menu display is automatically executed and can be used. However, when the original optical recording disk 2 is copied to the single-recording or double-layer recording general-purpose optical recording disks 5 and 6, a predetermined process such as menu display is not performed, and the use can be prevented.

  Further, the optical recording disk 2 of the present embodiment is configured to simply add the activation designation file 18 and the activation file 19 to the data 20 and store them, and it is not necessary to perform special processing on the stored data 20. Thereby, cost saving is achieved and the data 20 is not deteriorated. Moreover, it is preferable for a data provider from the viewpoint that data is not processed.

  Further, according to the present embodiment, it is possible to reliably prevent the use of the copied disc without depending on the deck on which the disc is mounted or the processing on the player side.

  In the present embodiment, the startup file 19 is stored in the enlarged recording area 15, but a configuration in which a part of the startup file 19 is stored in the enlarged recording area 15 can also be adopted. Further, it is possible to adopt a configuration in which a part or all of the activation designation file 18 is stored in the enlarged recording area 15 instead of the activation file. Furthermore, it is possible to adopt a configuration in which a part or all of both the activation file 19 and the activation designation file 18 are stored in the enlarged recording area 15.
