Abstract

PURPOSE:To easily reproduce plural reproduced disks by a simple device by reading recorded information while turning a discoid information storage medium, and then writing the read information on a medium for stored information reproduction or its original disk. CONSTITUTION:An information storage medium 1 is turned by a medium driver 7, and a medium 4 for stored information reproduction or its original disk 4' is turned by a medium driver 8. Motor driving circuits 13 and 14 rotate the information storage medium 1 and medium 4 for stored information reproduction or its original disk 4' synchronously through a rotation synchronism control circuit 15. A read signal obtained by an optical head 16 for reading information is converted by a control circuit 18 into a write signal, which is outputted to an optical head 17 for writing information, which writes the information on the medium 4 or its original disk 4', thus easily obtaining plural reproduced disks by the simple device.
