Optical disc recording apparatus and optical disc reproducing apparatus

Claim 1

A disc recording apparatus for recording input data on a series of disc-shaped recording medium, comprising: memory means in which continuously inputted input data are sequentially written and from which the input data are read out as recording data at a transfer rate faster than the transfer rate at which the input data are written therein, recording means for recording the recording data read from the memory means on a first disc-shaped recording medium and then a second disc-shaped recording medium, each of the first disc shaped recording medium and the second disc-shaped recording medium being rotationally driven at a predetermined velocity, recording controlling means for effecting readout control of the memory means so that, when the data volume of the input data stored in the memory means exceeds a first predetermined volume, the recording data f the first predetermined volume is read out continuously from the memory means so that a writing space in excess of a second predetermined volume is maintained at all times in the memory means, the recording controlling means also effecting recording position control so that the recording data of the first predetermined volume read out in a burst-like manner from the memory means by the readout control of the memory means are continuously recorded on a recording track on the first disc-shaped recording medium and then on a recording track on said second disc-shaped recording medium, and linking controlling means for capturing control of a recording system of the second disc-shaped recording medium during a time interval between when data are last recorded on the first disc-shaped recording medium and data are next read from the memory means so that data are continuously recorded on the first disc-shaped recording medium and on the second disc-shaped recording medium.
