Patent ID: 8203923

Claim:
A recording device for an optical recording medium which records and reproduces an information signal, the recording device comprising: a recording signal processing circuit which, by adding an error correction code for error correction at a time of reproduction, to supplied recording data, generates a recording code according to a code occurrence frequency; a write pulse generation circuit which generates a write pulse for recording, based on the recording code supplied from the recording signal processing circuit, on the optical recording medium and an erase top pulse having a leading edge coinciding with a trailing edge of the write pulse; a laser diode drive (LDD) for power-amplifying the write pulse and the erase top pulse generated by the write pulse generation circuit; an optical pickup including a laser diode (LD) for recording information by irradiating the optical recording medium with a laser beam based on the write pulse and the erase top pulse supplied from the LDD; and a system control circuit for controlling each element of the recording device.
