Video data and audio data inputted respectively from a camera system (1) and a microphone (4) are compressed and encoded in a video compressor/expander-encoder/decoder (2) and an audio compressor/expander-encoder/decoder (5) respectively, and then are multiplexed in a multiplexer (7). Subsequently the multiplexed data are supplied to a hard disk drive (14) via an AV interface (8), a host bus (15), an interface adaptor (12) and an interface (13). Information representing the kind of the data is written in a register (14a). The data supplied to the hard disk drive are recorded in a disk (22), on the basis of such information, by a method conforming with the data. And in a reproduction mode, the data are reproduced, on the basis of such information, by a method conforming with the data. Thus, the data can be recorded or reproduced efficiently by the relevant method conforming with the kind of the data.
