摘要:
A device for searching a target time code recorded on a disk with continuous frame addresses includes: a pick up (1) for reproducing information including current time code and current frame address corresponding to a current reproduction position of the pickup from the disk, unit (21) for calculating a time code difference between the target time code and the current time code reproduced by the pickup, unit (12, 13) for setting a target frame address on the basis of the calculated time code difference and the current frame address reproduced by the pickup, unit (8) for calculating shift information including a shift distance and a shift direction from the current reproduction position to the position of the target frame address on the basis of the target frame address and the current frame address, unit (10, 11) for shifting the pickup on the basis of the shift information, unit (7) for storing the current frame address when the shifting unit shifts the pickup in an outer peripheral direction of the disk, and unit (9) for allowing the pickup to continuously reproducing information from the disk from the position of the current frame address stored in the storing unit when the shift distance becomes within a predetermined distance value or when the time code difference becomes within a predetermined difference value until the current reproduction position reaches the reproduction position whose time code is near the target time.
