摘要： To improve the reliability to an environmental temperature change of an optical pickup, an optical pickup 7 has a semiconductor laser 711 for generating a laser beam. An objective lens drive leads the laser beam to a predetermined position of a disk. The semiconductor laser and objective lens drive are mounted on a pickup hosing 70. The objective lens drive has a movable portion 74 and the movable portion has an objective lens 716 for condensing the laser beam on the recording face of the disk. A fixed portion 72 holds the movable portion through a support member. The fixed portion has a magnetic yoke 75. An extended portion formed by extending a part of the yoke to the fixed portion side and the upside 72b of a cutout formed at the intermediate portion of the fixed portion in the tracking direction are adhered and fixed.

摘要： An optical pickup having a case made of a resin material reinforced with glass fiber, inorganic filler or the like with polyphenylene sulfide as a base material, and a metal plate formed of a material having a linear expansion coefficient within a range of a linear expansion coefficient of the case in a direction between bearings when a fiber orientation of the case is along the direction between the bearings or random. The metal plate has two rising members bended to the case side at both ends in the direction between the bearings. Two walls of the outer hull of an opening of the case at both ends in the direction between the bearings and the two rising members of the metal plate are alternately opposed, and the opposed walls of the case and the rising members of the metal plate are fixed using adhesives.
