ABSTRACT:
An optical disc recording/reproducing apparatus capable of performing the operation of recording, reproducing, or recording and reproducing a plurality channel of signals efficiently and in a short time, by controlling memories. The apparatus has a compressor for compressing an input signal supplied via an A/D converter, a first memory for storing the compressed signal, a disc recording unit having a modulator for modulating the compressed signal and a head block for recording the modulated signal on an optical disc, a disc reproducing unit having a demodulator for demodulating the compressed signal read from the optical disc by the head block, a second memory for storing the demodulated signal, an expander for expanding the demodulated signal read from the second memory, and a D/A converter for converting the read signal.
