Abstract
A gain setting method for setting a gain in an amplifier that amplifies signals obtained from an optical disk, which includes: a measuring step for measuring an output level of the amplifier; and a gain setting step for setting the gain as the value of the target level/output level, when the measured output level is in a range of 1/N times and N times (N is an integer of 2 or larger) with respect to the preset target level.
