Abstract
A voice file consists of a plurality of data blocks. Each data block is composed of a plurality of sectors. Playback time information on voice data recorded in the sector is stored in the sector header. A control device creates a management file having the playback time for each block recorded therein from the information on this sector header, and stores it in a RAM or storage medium. When an arbitrary playback time is specified by an input device, which of the data blocks having the specified playback time positioned therein is retrieved by referring to this management file. Then, the playback times of voice data in sectors are calculated sequentially from the first sector of the data block. A sector in which a sum between the calculated playback time and a playback time up to a data block immediately preceding the retrieved data block is coincident with the specified playback time is retrieved, and access to the sector is provided.
