ABSTRACT:
A disk memory device is provided that measures a time for reading or writing a prescribed amount of data with an access time measurement part, compares access time data with a previously set limit time with an access time defect determining part, and, when the access time data exceeds the limit time, determines that a corresponding area on a disk memory (4) is defective, and enters the area into a defect list so that the corresponding area is not used. Thereby, when the disk memory device is used for recording/reproducing AV data, data access is performed within a prescribed time, so that videos are reproduced without interruption or data is recorded without lack of frame.
