Abstract
A disk playback device including a memory for temporarily storing data from a pickup and outputting the data as delayed by a predetermined period of time, manual keys, and a system control circuit for detecting the playback end of a disk from the playback data from the pickup. The memory has connected thereto an erase circuit for erasing data remaining in the memory. The system control circuit produces different flag values in a first case wherein the control circuit detects the disk end to terminate playback of the disk and in a second case wherein the user manipulates one of the manual keys to terminate the playback. A memory control circuit is connected to the memory and the system control circuit. In the first case, the memory control circuit inputs to the memory playback data of another disk replacing the disk as continued from the data remaining in the memory. In the second case, the circuit inputs to the memory the playback data of another disk replacing the preceding disk after the data remaining in the memory is erased by the erase circuit.
