摘要： A recording/reproducing apparatus includes: a light source; a first correction section to correct a position of an objective lens that collects laser light from the light source on a surface of an optical disc based on a focus bias setting value obtained from a focus bias value; a second correction section to correct an aberration of the laser light based on an aberration correction setting value obtained from an aberration correction value; an evaluation value generation section to generate an evaluation value; a focus bias adjustment section to change plus/minus of the focus bias value and calculate a new focus bias value based on the evaluation value every time a first cycle passes; and an aberration adjustment section to change plus/minus of the aberration correction value and calculate a new aberration correction value every time a second cycle passes, in parallel with an update of the focus bias value.

摘要： A recording/playback apparatus includes an optical head unit, a laser drive pulse generator, a power setting unit, an evaluation value calculator, and an adjustment controller. The adjustment controller performs control such that recording operations for adjusting laser drive pulses are performed on an optical recording medium by changing the adjustment setting for the laser drive pulses to different adjustment setting conditions under a condition that each of two or more levels of power of the laser light is set to obtain a quality evaluation value for each adjustment setting condition, and determines the adjustment setting for the laser drive pulses on the basis of the obtained quality evaluation value, and sets the determined adjustment setting in the laser drive pulse generator.
