Embodiment Construction

[0067] Hereinafter, the configuration and operation of a preferred embodiment of the disk / disk drive management system of the present invention will be described in detail with reference to the accompanying drawings.

[0068] The present invention uses an optical disc equipped with an electronic circuit having a central processing unit (CPU) function. However, the present invention is not limited to this optical disc, but any disc can be used.

[0069] FIG. 1 is a schematic block diagram showing the basic configuration of a disk / disk drive management system according to the present invention. In the following examples, as a disk to which the present invention is applied, an optical disk is used. In this system, a disc drive 1 rotates an optical disc, reads content from or writes data to the optical disc. The data storage section provided on one side of the optical disc is used to store optical data such as content and the like. The other side of the disc is equipped with an...

Abstract

There is provided a disk / disk drive management system that is capable of setting limits to reproduction of a disk and a disk drive used for the disk reproduction, for example, setting limits to reproduction of a rental disk to prevent unrestricted copying. On a first storage region of a disk having optical information written thereto and a second storage region of the disk having an electronic circuit 11 mounted thereon, a plurality of arbitrary codes (A001 to A999) assigned uniquely to the disk are stored. When the disk is loaded into a disk drive 1, the plurality of codes are read in and written to a code memory 114 of the electronic circuit 11, and an unused code of the plurality of codes is written to a memory 14 provided in the disk drive 1 and / or to a management memory 115 provided on the electronic circuit 11. The disk drive information that was used or is being used, user information, and other information can also be written to the management memory 115. The reproduction of the disk, and the disk drive used for the disk reproduction, are controlled based on the information written to the memory 14 or management memory 115.

Description

technical field [0001] The present invention relates to content management systems and, more particularly, to disk / disk drive management systems for securely limiting the reproduction and utilization of content stored on a disk. Background of the invention [0002] With the appearance of these large-capacity storage media such as compact disk (CD), digital video disk (DVD), it has become common to store content such as music, movies, and game software on these storage media. In CDs and DVDs, music and movies are recorded in specialized formats, so that if simple data copying is performed with a computer or the like, it is impossible to reproduce music and movies from the copied data. [0003] On the other hand, when the above-mentioned special format processing is not performed on the contents stored on these storage media, the contents can be copied without restriction if there is no special authentication means. From the viewpoint of copyright protection, this will become...
