Abstract
An optical disk drive apparatus has an objective lens which converges a light beam to direct it to an optical disk, an objective lens support, an elastic support member which movably supports the objective lens on the objective lens support portion, and a coil and a magnet. The coil and magnet are capable of moving the objective lens against an elastic force of the elastic support member relative to the objective lens support portion so as to vary an angle of incidence of the light beam emitted from the objective lens with respect to an irradiated surface of the optical disk. The angle of incidence is adjusted by an electric power supplied to the coil.
