Recording apparatus for optical recording media

摘要

A recording apparatus includes a gate signal generator for generating a gate signal in accordance with the data signal; a pre-pit signal generator (14) for generating a pre-pit signal from a signal read from the recording medium; a gate circuit (31) for generating a pre-pit pulse train by allowing the pre-pit signal to pass therethrough in response to the gate signal; a pulse extractor (30) for extracting pulses of predetermined waveform from the pre-pit pulse train; and a synchronization signal generator (17) for generating a recording synchronization signal based on the pulses of predetermined waveform.
