Patent ID: 6868053

Claim:
An optical information recording and reproducing apparatus which records information by emitting a laser beam that is modulated according to recording data to a recording medium, said apparatus comprising: a laser light source operable to emit a laser beam to a recording medium; a recording pulse generator operable to generate recording pulse signals so as to modulate an optical intensity of the laser light source according to recording data; a laser driver operable to drive said laser light source according to the recording pulse signals generated by said recording pulse generator; a photodetector operable to detect the laser beam emitted by said laser light source; a sampler operable to sample an output signal of said photodetector; and a sampling timing generator operable to generate a sampling timing to instruct sampling to said sampler; wherein said sampling timing generator is operable to generate a sampling timing which is delayed by at least a response time of a propagation path including said laser driver, said laser light source and said photodetector.
