ABSTRACT:
A recording and/or reproducing apparatus reproduces the area for reproduction only of a composite disc composed of the area for reproduction only and the recordable area by using one recording and/or reproducing head via a first memory, and records the external input data in the recordable area of the composite disc via a second memory. At this time, the writing speed of reproduced data to the memory is set faster than the reading speed of data from the memory, so that the reproducing operation is intermittently performed in accordance with the memory capacity. In intermittent operation, by moving the recording head to the recordable area of the composite disc to start to record, the voice information of user is mixed in the reproducing information of the area for reproduction only, and the mixed signal can be recorded in the recording area again.
