An audio signal and a video signal are recorded onto a hard disk. In the hard disk, by time-divisionally processing the recording and reproduction, they are executed in parallel. Audio data as much as four fields and corresponding video data as much as one field are constructed as one set and are time-sequentially recorded. In a one-time speed reproduction, the data is reproduced every set. The video data is repetitively reproduced for a period of time of four fields. In a double-speed reproduction, the video data is reproduced every other data and the audio data as much as four fields corresponding to the video data which is reproduced and the audio data as much as subsequent four fields are reproduced. To reproduce the audio data as much as eight fields for a period of time of four fields, the speed of the audio data is converted to a double speed and the audio data is continuously reproduced.
