Patent ID: 8355310

Claim:
An optical information recording method for recording information by emitting a pulsed laser beam from a laser light source and thus forming a recording mark on a recording medium, the method comprising the steps of: acquiring information on temperature, a recommended recording power of the recording medium and a differential resistance of the laser light source to be used; obtaining a register value corresponding to the acquired information, by referring to a table in which a register value to be set in a waveform control register of a laser driver which drives the laser light source is stored in association with a combination of the temperature, the recording power and the differential resistance of the laser light source; setting the obtained register value in the waveform control register of the laser driver; adjusting at least one of a rise period and a fall period of a light-emission pulse; and recording information by forming a strategy with a pulsed laser beam generated from the laser light source driven by the laser driver.
