Claims

[Scope of Claim for Utility Model Registration] (1) In an optical disk storage case of an optical disk recording device in which a write-once optical disk is stored in a storage case and is installed in a recording and playback device to perform recording and playback, the optical disk is placed in the storage case. An optical disc characterized by comprising a storage space, a solid-state memory capable of recording and erasing, and a connection means for receiving and passing power, data, and control signals between the main body of the recording and reproducing device in an attached state. The optical disk storage case according to claim 1, wherein the storage case (2) is an electrically erasable read-only memory. (3) The optical disk storage case according to claim 1, wherein the solid-state memory is a magnetic bubble memory. (4) Utility model registration claim 1, characterized in that the above-mentioned solid-state memory is an ultraviolet erasable read-only memory, and the storage case is provided with a window for transmitting ultraviolet rays on the solid-state memory. Optical disk storage case described in section.
