Adjusting optical disk for adjusting optical pickup, adjusting method of optical pickup, and adjusting device for optical pickup

摘要

A light source having a drive portion for driving a light source for emitting a beam light, an objective lens for irradiating beam light onto an optical disk for adjusting an objective lens and an objective lens for driving an objective lens in a direction parallel to the optical axis of the objective lens and a direction perpendicular to the optical axis, are provided with a light source to an objective lens The driving part is held movably with respect to the light source, and the beam is irradiated onto the adjustment optical disk having a recording track concentrically concentric from the optical pickup, and the phase of the objective lens with respect to the light source. A method of adjusting an optical pickup for adjusting a pair position and an inclination of the optical axis of an objective lens and an optical disk for adjustment used in the adjusting method.
