Abstract

PURPOSE: To simplify the CM transmission system unit, by recording the track or head number corresponding to the length of CM information in the sectors split into a plurality for the digital audio disc.
CONSTITUTION: Several turnks from the outer to inner circumference of the disc 6 are taken as the cylinder address storage space 8, and the audio storage space 9 is taken to the inner circumference succeeding to it. When power is On at readout, the cylinder address storage space 8 of the disc 6 is read, the address collation memory 2b sets the spot number, and track and head collation memory 2C sets the track and jead number SCAD. At this time point, when the address indication is made, the cylinder address storage space 8 of the disc 6 is read out, and the head 7 is shifted to specified track position for readout. Thus, the CM transmission system unit can be simplified.
