Patent ID: 8395979

Claim:
A recording device comprising: a light irradiation portion which irradiates an optical recording medium with laser light emitted from a light source via a field lens; a light emission drive portion which drives and causes the light source to emit light; a front monitor which receives the laser light emitted from the light source; a light receiving portion which receives reflected light which is obtained from the optical recording medium in response to the laser light irradiation; a focus servo control portion which controls a focus servo of the field lens on the basis of a light receiving signal by the light receiving portion; a surface jump controller which controls the focus servo control portion so as to perform a focus jump operation to a surface of the optical recording medium in a state in which a focus servo is applied to a recording layer of the optical recording medium; and a surface APC corrector which performs a process as an auto power control (APC) correction process in a state in which a focus servo is applied to the surface due to control by the surface jump controller, wherein the process includes changing a value of a laser driving current which is supplied to the light source from the light emission drive portion, and obtaining a laser driving current value corresponding to each of a plurality of target laser power, and setting a gain on the basis of a plurality of the laser driving current value corresponding to each of the plurality of target laser power as a gain to be given to a laser drive signal for driving and causing the light source to emit light.
