Inventor: SENBOKU KAZUHIRO
IPC: G11B7/00
Filed: 1990-10-31
Abstract: PURPOSE:To make clear whether a maker is responsible or not and to comply with the unfair claim of a user simply and accurately by a method wherein an identifier regarding an optical disk drive unit is recorded on a surplus part following a user data part on an optical disk. CONSTITUTION:Such pieces of information as peculiar information on a maker who has manufactured an optical disk drive unit, information on a type name and information on a production No. are stored in an identifier generation circuit 4. An identifier signal S7 by means of a pattern for identification use is output from the circuit. When a data at a user data part on an optical disk is read out and an identifier in a surplus part following it is read out, they are read out from the optical disk 11 by using a laser pickup 10, and are input to a read circuit 8 as a read data S11 before a waveform is reshaped. Thereby, when a trouble such as a read error or the like is caused, it can be known accurately whether the trouble is caused on the drive unit manufactured by the maker or not by referring to whether the identifier exists or not and by referring to its content and its state.
