ABSTRACT:
The system for supplying information to a terminal device or devices has one or more optical disk drives, a magnetic disk storage for storing information regarding a beginning portion of the information recorded on the optical disk or disks, one or more optical disk monitoring circuits, an electronic switch assembly for selectively outputting one of the stored information from the magnetic disk storage and the readout information from the optical disk drive, one or more FIFO memories for temporarily holding and outputting information from the electronic switch assembly, and a controller which causes the electronic switch assembly to output the stored information from the magnetic disk storage in response to the playback request input, and subsequently causes the electronic switch assembly to output the readout information from the optical disk drive in response to the signal from the optical disk monitoring circuit so that the FIFO memory outputs continuous information.
