PROBLEM TO BE SOLVED: To achieve a continuous smooth moving image playback which reduces the number of seek occurrences when reading a large size file such as a moving image in an image and sound record/playback device which mounts a HDD (hard disc drive) and plays back image/sound data recorded in this HDD. SOLUTION: Continuity of data in a file written in a disk is secured in units of a big cluster by managing the file such as the moving image data that is read/written to the hard disk drive in units of cluster by FAT file system and by reading/writing the file in units of the big cluster composed of two or more consecutive clusters.
