Abstract:
A recording device including: an optical head section for irradiating a recording medium with laser to record and reproduce information; a laser driving section for driving the optical head section to output laser; and a control section for, in a process of adjusting recording laser power output from the optical head section, obtaining an evaluation value of a recorded area after a predetermined period of time elapsed since data was recorded as an evaluation value about a reproduction signal during reproduction of the recorded data, and adjusting recording laser power on the basis of the evaluation value after the predetermined period of time elapsed since data was recorded.
