ABSTRACT:
An optical disc recording apparatus for dividing an information record surface of an optical disc into a plurality of record zones and recording information at a data rate which differs for every record zone, is provided with: a drive device for rotationally driving the optical disc by a constant angular velocity; a frequency conversion device for converting a clock frequency of input clock data corresponding to record data inputted from the external which is to be recorded on the optical disc, to record clock data corresponding to the record zone to be recorded, and outputting the record clock data; a memory device for storing the record data by a timing corresponding to the input clock data, and outputting the record data on the basis of the record clock data; and a record device for recording the record data outputted from the memory device, to the optical disc.
