A nonvolatile memory chip 106 is embedded and mounted in and at the part 103 not recorded with the data in the central part of an optical disk substrate and is subjected to wiring 107 in such a manner that the mutual contact of the recording surface 105 with the opposite surface 104 is averted.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a read-only memory ROM such as an optical disk used for storing music, images, text data, numerical data, etc. The present invention relates to a ROM that can store personal information.

[0002]

2. Description of the Related Art Conventional playback-only optical disks used for storing music, images, text data, numerical data, etc. are suitable for mass data distribution, but their contents cannot be edited or changed. there were. For example, intermediate results of a game in a read-only memory CD-ROM using a compact disc used in a home-use game dedicated machine, data of a music selection program of an audio compact disc CD, and the like are stored on the drive side. Therefore, if the drive is different, the saved result cannot be used at all.

On the other hand, a magneto-optical disk is known as a recording medium capable of recording a large amount of information, but it needs to be initialized for recording, and it takes a long time to record data, resulting in a troublesome data recording. Considering the cost, it was unsuitable for the purpose of distributing a large amount of data.

[0004]

The object of the present invention is to distribute a large amount of data, but solves the problem of a read-only type optical disc in which the contents cannot be edited or changed, and the conventional optical disc An object of the present invention is to provide a recordable compact disc that can store data without sacrificing ease of handling and compatibility.

[0005]

In order to achieve the above-mentioned object, the present invention provides a read-only optical disc used for storing music, images, text data, numerical data, etc. A memory chip is embedded and a contact terminal with an external terminal is provided on the surface opposite to the recording surface of the optical disk, enabling the user to save data.

[0006]

In a CD or CD-ROM, a thin flash memory is mounted on the label surface, and access terminals are arranged concentrically in the center of the disk, thereby reducing the conventional CD and C.
Data can be stored without impairing the convenience of handling the D-ROM.

[0007]

FIG. 16 shows an embodiment in which the present invention is applied to personal backup data.

CPU 1601, keyboard 1602, pointing device 160 such as mouse and joystick
3, a display 1604, a ROM 1605, a sound source 1606 such as a built-in or an external synthesizer, a magnetic disk device and disk data 1607 stored therein, an information recording medium drive 1608 of the present invention, and an RAM 1609. The optical disc portion 105 of the medium 101 is a write-once or erasable medium 1611 that can be recorded in the same format as a read-only optical disc used for storing music, images, text data, numerical data, etc. To store. The memory chip 106 stores the directory information 1611 of the optical disc portion and the access permission information 1612 of the backup data. By storing the directory information 1611 only in the memory chip 106 without storing it in the optical disc portion 105, it becomes impossible to read data in the conventional optical disc drive.

FIG. 17 shows the information storage structure in the memory chip 106 in the application to personal backup data. The directory information 1611 of the backup data of the optical disk portion 105 is stored in the memory chip 106, and the access permission information 1611 in the memory chip 106 corresponding to the optical disk portion 105 is the backup data information 1701 and the backup data password 1702.
It is divided into The backup data information 1701 stores information necessary for the user to refer to the backup data later, such as the pointer to the optical disc portion 105 and the date and time of the backup. Password 17
02 is specified by the user and stored.

The backup procedure is shown in FIG. After starting the software used for backup and selecting the backup file (1801), the memory chip 10
Backup information 1 in access permission information 1612 of 6
The backup date and time, contents, etc. are stored in the portion 702 (1802). Next, enter the password for access (1803) and store the entered password (1
804). After that, backup processing is executed (180
5) Finally, the directory information of the optical disc portion 105 is stored in the memory chip portion 106 (1806).

FIG. 19 shows the procedure for restoring the backed up data. When the restore process is executed, the backup data list is displayed first (1901),
Backup data to be restored is selected from them (1902). Next, the password for the selected backup data is input (1903). Next, the password is checked (1904), and if the password is correct, restore processing is executed (1905).

As described above, by applying to the backup of personal data using the information recording medium of the present invention, the data cannot be read unless the password set for the backup data is input, thereby making it unspecified. Disables access to large numbers of data. In addition, even if the password is leaked, the license password can be changed, preventing unauthorized use of the password. Further, by storing the directory information 1611 of the optical disc portion 105 in the memory chip 106, it is possible to prevent the reading of data by the conventional optical disc drive.

2006, an audio CD player comprising an information recording medium drive 2007 of the present invention, an optical disc portion 2008
Stores music information in the same format as a conventional audio CD. The memory chip 106 stores a memo 2009 of each song and program data 2010. Next, the information storage structure in the memory chip 106 in the application to the audio CD in which n pieces of music are stored will be described.

FIG. 21 shows an information storage structure in the memory chip 106 in the application to the audio CD. In the portion of the memo 2009 in the memory chip 106, information 2101 such as the title of the song and the performer is stored. In the program data 2010, a music order 2102 of a favorite music selection is stored.

Audio CD on the information recording medium of the present invention
FIG. 22 shows the reproducing procedure of the above. When the disc is inserted into the player, the memo and the program data are read from the memory chip 106 (2201). A program list is displayed based on the read data (2202), and the user selects a program with a desired song selection (2203). Then, the performance is started according to the program (2204).

When the information recording medium of the present invention is applied to an audio CD, the optical disk portion is a conventional audio CD.
Therefore, the conventional CD player, which cannot read the memory chip, can handle it like a conventional CD. If a player capable of reading the music selection program of the memory chip is used, it is possible to enjoy a desired music selection without reprogramming even in a room stereo or car stereo, for example.
