Technical Examples

A spherical aberration correction control device for controlling a spherical aberration correction section for correcting a spherical aberration of an optical beam irradiating an optical disc. The spherical aberration correction control device includes a spherical aberration control signal generation section for generating a spherical aberration control signal; and an output section for outputting the spherical aberration control signal to the spherical aberration correction section. A correction amount by which the spherical aberration is corrected is changed by the spherical aberration correction section in accordance with components of the spherical aberration control signal. The spherical aberration control signal generation section generates the spherical aberration control signal such that a sum of correction amounts corresponding to the respective components of the spherical aberration control signal becomes substantially zero with respect to a target correction amount.
