Patent ID: 7266068

Claim:
A method of controlling an optical disk apparatus, comprising: causing a light emitting unit to emit a test laser beam having a pulse width broader than a pulse width used at a time of recording; causing a light receiving unit to receive the test laser beam and to output a first detection signal; generating a first control signal by comparing a value held at a peak level of the first detection signal with a target value of a quantity of the test laser beam; generating a second control signal by comparing the first detection signal with the target value of the test quantity of the test laser beam; determining and storing a correction amount for equalizing the first control signal and the second control signal when the first control signal and the second control signal are not equal to each other; and controlling the quantity of light of a recording laser beam by correcting a recording control signal generated in accordance with a recording detection signal from the light receiving unit by means of the correction amount and by supplying the corrected control signal to a driving unit of the light emitting unit when information is recorded onto an optical disk.
