摘要： 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.

摘要： A holder holds a mini-disc cartridge and mounts the disc on a turntable. An optical pickup transport holding an optical pickup for applying a laser spot to a signal record track of the disc is movably supported by a guide rod. A magnetic head contacts the disc and applies a magnetic field to the back surface of the disc where the laser spot is applied. A switch judges whether the data record to the disc is to be permitted. The magnetic head is pushed against the disc only when the mounted disc is permitted to record data and the data record is to be performed.

摘要： In a disc changer, improvements of the taking-out operation, housing operation, stabilization of disc transfer and downsizing of a conveyance mechanism and stabilization of reproducing operation are intended. The disc changer comprises a disc housing unit, a disc transfer mechanism provided on the upper surface of the disc housing unit, and a disc playback unit. The disc housing unit 100 is provided with disc exchange support mechanism for pushing up a disc inside disc housing groove 101 formed in the disc housing unit and light-emitting means 107 for allowing groove 101 to be recognized.
