Abstract
An optical disc recording apparatus in which audio data obtained by digitizing analog audio signals and time base compressing the resulting digital audio signals are read from a buffer memory on the cluster-by-cluster basis so as to be recorded on a recording track of a first optical disc and then a second optical disc. During the time interval when a cluster audio data unit next to the last cluster audio data unit written on the first optical disc by a first optical disc driver 14 is read from a memory 14, a second optical disc driver is captured into synchronization for continuously recording audio signals on the first and the second optical discs under the control of a system controller.
