摘要： Additional information for each musical program is automatically recorded on an optical disc. A digital voice signal reproduced from a mini-disc is sent to an MD system via a digital voice signal line and recorded on another mini-disc. Additional information such as the title of a musical program is sent via a serial communication line 6 to a MD control microcomputer and stored in its RAM which stores U-TOC information. The U-TOC information stored in RAM is recorded on the mini-disc before it is dismounted from the MD system.
