DISK REPRODUCING DEVICE AND ITS INTEGRATED CIRCUIT

摘要

PROBLEM TO BE SOLVED: To deal with standard speed reproduction in an N-time faster high speed operation mode as well as an intermittent access caused by track-jumping in a conventional CD reproduction system. SOLUTION: A disk reproducing device is provided with a memory 11 for writing data reproduced from a disk 1 and time information together in correspondence, and another external memory 15. A time difference between data 17 to be finally outputted and data 13 under access is detected in a time information detection circuit 18 of an address control circuit 19 to detect the overflow and underflow of the external memory 15. The write of the external memory 15 is controlled on the basis of the detected result. The correctly connected and continued data 17 are obtained at the time of output by absorbing the time difference between a system operation speed and a data output speed even in the case of performing the intermittent access by controlling a pickup 4.
