发明名称 REPRODUCING DEVICE OF DISK DATA
摘要 PURPOSE:To make unnecessary to input program data again even afer an electric power supply for the titled device has been disconnected by providing said device with a controlling device reproducing a program for a charged disk using the program data corresponding to discriminating data stored in a storage device. CONSTITUTION:When a power supply switch 11 in the reproducing device is turned on and a disk to be reproduced is charged, a pickup part is accessed on a lead-in track at first to read specific data specified as the discriminating data of the disk. A CPU31 compares the read data with disk discriminating data stored in an RAM32 in the reproducing device which is not erased through the disconnection of power supply, and when both data coincide with each other, the contents of a reproducing program of the newly charged disk which is stored in the RAM32 are not changed or cleared is checked and then reproducing is started on the basis of the reproducing program. If the change of the program is specified, reproducing operation is executed on the basis of the changing indication.
