Abstract
A high speed dubbing is to be realized with two recording and/or reproducing units for compressed data. To this end, a magneto-optical disc,is read by an optical head,and compressed data produced via a decoder,are delivered to a memory,via a switch,. The data are then delivered to a magnetic head driving circuit,via an encoder,for direct writing on a magneto-optical disc,. In this manner, compressed data are directly dubbed without expansion to realize high speed dubbing.
