A recording/reproducing unit changes the number of sectors of the disk type recording medium within a predetermined number of sectors to record the audio signal stored in the storage unit in synchronization with the image signal. A memory unit memorizes information of the sectors of the disk type recording medium on which the audio signals have been recorded as management information. The recording/reproducing unit reproduces the audio signal recorded on the disk type recording medium in synchronization with the image signal in accordance with management information memorized by the memory unit.
