Abstract

PURPOSE:To freely vary reproduction speed, by recording information on a medium after applying time base compression, and varying the readout rate of a storage means where the reproduction information is stored. CONSTITUTION:The time base of analog recording information is compressed by a prescribed compression rate in a time base compression part 10, and the information is recorded on a master disk 22 as a pit, and a CD24 is manufactured based on the above recording. From the CD24 compressed and recorded in such way, the pit is detected at a decided transfer rate by an optical head 28, and reproduced information is stored in a memory circuit 32 transiently at the decided transfer rate, and is read out at an arbitrary transfer rate. The readout rate is controlled by a transfer rate variable control part 31 based on the operation of a reproduction speed setting device 29. In such a way, only by varying a part of the transfer rate, it is possible to vary the reproducing speed.
