Abstract
An optical pickup has a suspension base, a holder suspended from the suspension base by wires in a form of a cantilever. The optical pickup is slidably mounted on a guide shaft. The guide shaft is pivoted so that an optical axis of an optical system becomes perpendicular to an optical disk. The holder is provided to be tilted in a radial plane with respect to the optical disk when the holder is moved for focusing the optical system.
