Abstract

PURPOSE: To prevent degradation and damage, by using an optical disc as the print mother and by using the optical disc reproducing device as the reproducing device for mather and by making it possible to reproduce signal without contact for the optical disc which becomes the print mother.
CONSTITUTION: The original sound signal supplied from sound signal source 9 is converted to a digital signal by PCM encoding circuit 11 and is supplied to optical disc recording device 12 and is recorded onto optical disc 13. At this time, the signal is recorded while rotating optical disc 13 as slowly as possible in the allowable range of the recording density. This optical disc 13 is sent to the print plant, and optical disc 13 is used as the print mother and is set to optical disc reproducing device 14, and the recorded digital signal is reproduced while rotating optical disc 13 as quickly as possible. Thus, the high-speed sound signal can be obtained in the speed several tens times as high as the recording speed.
