Abstract

PURPOSE: To allow the recording of fresh program information from right after an end position by moving a pickup to the end position when discrimination is made that pause information is recorded after the final recording position.
CONSTITUTION: A recording operation control circuit 5 emits the search command up to an unrecorded part when discrimination is made that the information is recorded even after the searched final recording position. A search circuit 8 drives a tracking control system 4 and a slider servo system so as to move the pickup 2 in the outer peripheral direction of a disk. The search operation is stopped and whether the recording information just before the searched position is the pause information or not is discriminated when a detection signal is generated from a detecting circuit 20. If this information is the pause information, this point is the position to start recording of the fresh program information and, therefore, a flat F is set and the operation is shifted to the next step.
