Abstract
High rate writing of data recorded on a CD into a hard disk drive (HDD) is performed while reproducing data read out of the CD at the standard bit rate prescribed for the CD. PCM data corresponding to a playback time of 10 seconds, for example, is read out of a CD and stored in a memory for subsequent read out. In parallel, data for writing is read out of the CD and stored in the memory. The data read out of the memory is coded and compressed by an encoder and then stored back in the memory. When the data stored in the memory for playback has become smaller than a predetermined amount, an interrupt is generated during the writing process with the processing, which is given top priority, so that a next set of playback data is read out of the CD and stored in the memory.
