PROBLEM TO BE SOLVED: To enable dealing with recording/reproducing of plural formats in which rates are different and to suppress increase of the redundancy, with hardware of a small scale. SOLUTION: Respective lengths of data packet of video data and data packet of audio data is made different and set to optimum for plural formats in which video rates are different. Thereby, a circuit for record processing with respect to plural formats can be used as a circuit for reproduction processing. Also, since audio does not depend on a video rate and a picture frame, a video rate can be adjusted without changing audio signal processing. Further, since two video data packets can be stored in one Sync block, the recording efficiency can be improved.
