ABSTRACT:
An optical recording system wherein the record carrier is pre-recorded with adjustment information indicative of the waveform of the write signal (V.sub.s) to be employed for recording an information signal (V.sub.i) thereon. The recording apparatus includes a read/write head for reading the adjustment information before recording, and a control circuit for deriving the write signal (V.sub.s) from the information signal (V.sub.i). The control circuit includes an adjustment circuit which selects a write signal waveform in conformity with the adjustment information read from the record carrier.
