ABSTRACT:
An apparatus for recording data on a post-writing basis onto an a write-once, read-many optical disc of the compact disc standard has a reader unit for reading first image data recorded on a first optical disc, an input unit for receiving second image data, and a recorder unit for recording image data onto a second optical disc. A control unit is provided for controlling the reader unit, the input unit and the recorder unit to cause the reader unit to read out the first image data from the first optical disc and to cause the recorder unit to record the first and second image data onto the second optical disc. The reader unit has verification circuitry for verifying the condition of the recording surface of the first optical disc to determine whether or not the surface is appropriate for recording of the second image data.
