Patent ID: 6873586

Claim:
An optical recording apparatus for recording a data pulse signal constituted by consecutive pairs of mark and space on an optical recording medium, comprising: a drive pulse generator for generating a drive pulse in response to the data pulse signal; a light source element for generating a write beam in response to the drive pulse; and an optical system for irradiating the optical recording medium with the write beam, wherein the drive pulse generator includes a write pulse generator for generating a write pulse signal based on the data pulse signal, a write beam intensity detector for detecting intensity of the write beam and generating a write beam intensity signal representing the detected intensity, an instruction pulse generator for generating a comparison signal representing a phase difference between the write pulse signal and the write beam intensity signal and for generating an instruction pulse which is obtained by regulating a pulse width of the write pulse signal in response to the comparison signal, and a drive unit for generating the drive pulse in response to the instruction pulse.
