ABSTRACT:
A disc recording/reproducing apparatus according to the present invention intermittently records and reproduces compressed digital audio data in normal recording/reproduction. In high-speed dubbing of digital audio data, two of such apparatuses are used, wherein compressed digital audio data is continuously reproduced from a disc for reproduction by the reproduction side apparatus to be directly applied to the recording side apparatus and continuously recorded on a disc for recording. Thus, the compressed high-speed dubbing of the digital audio data can be achieved without increasing a rotation speed of the disc even in high-speed dubbing.
