Optical disk cartridge

Abstract

Abstract PURPOSE:To quickly retrieve the presence/absence of the recording of a desired content by reading a semiconductor memory on which the directory of the recording content of an optical disk by a retrieval instruction from a sheet shape keyboard with a sheet shape electronic computer, and displaying a result. CONSTITUTION:The sheet shape electronic computer 50 is comprised of a RAM 13, a one-chip microcomputer 14, the sheet shape keyboard 15, and a liquid crystal display 16, and the directory of the recording content of the optical disk 12 is written in advance on the RAM 13 arranged at one side of the corner part at the back side of a cabinet 11. When an image is retrieved, an ID number, etc., is inputted with the sheet shape keyboard 15 arranged on the plane of the cabinet 11 of a cartridge, thereby, the one-chip microcomputer 14 reads in the directory recorded on the RAM 13, and performs a retrieval operation, and displays the result on the liquid crystal display 16. In such a way, it is possible to quickly retrieve whether or not the desired content is recorded on a built-in optical disk without loading the cartridge on a drive unit.
