<p>PURPOSE:To constitute a device in a small size not only reproducing data for a long time with uniform quality. CONSTITUTION:The data of image data, etc., recorded on an optical disk 1 is reproduced by a pickup 2, and is stored in a ring buffer memory 5 and decoded. At this time, the pickup 2 is track jumped corresponding to the storage amount of the data in the ring buffer memory 5 or the error of the data reproduced from the optical disk 1. Further, the error of the data reproduced from the optical disk 1 and stored in the ring buffer memory 5 is corrected by an error correction circuit 9.</p> |
