ABSTRACT:
The present invention provides an optical disc recording apparatus for recording on an optical disc which is preliminarily formed with recording tracks replaced in a track width direction in response to first data signals second data signals along the recording tracks in a track direction in which a desired recording speed is made selectable independently of the recording pattern of preliminarily recorded first data signals by changing the reference frequency when the disc rotation is controlled depending upon the speed during data recording so that the frequency of clocks obtained by reproducing the first data signals becomes a given reference frequency.
