摘要： PROBLEM TO BE SOLVED: To prevent uncured adhesive remaining at edges of adhesive surfaces of a magnet and a magnetic member from being transferred via finger cots, tweezers, etc. to optical pickups and contaminating them, thereby avoiding troubles in optical performance or in appearance which may decrease the yield.SOLUTION: A groove is formed on a surface of a magnetic member to which a magnet is to be fixed, where the depth of the groove is small near the center of the fixing surface and large near the outer circumference of the fixing surface. By this groove, an adhesive is drawn toward the center of the fixing surface by a capillary phenomenon and is prevented from spreading along the outer edge of the fixing surface. The corner of the groove is chamfered to reduce the adhesive remaining at the corner of the groove.

摘要： PROBLEM TO BE SOLVED: To provide an optical pickup including a lens-moving mechanism, wherein a moving sound is quiet and rocking of a movable lens is limited. SOLUTION: A nut having a flywheel attached to increase the inertial force is engaged with a lead screw formed in the rotary shaft of a motor. Thus, sliding occurs in a sliding part, between the lead screw and the nut for preventing application of a large rotational force on the nut, thereby reducing the collision force with a rotation-restricting member. The lens-moving mechanism reduces the operating sound due to the collision of the nut, and lens rocking due to the resistive force of collision. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an optical pickup with high reliability that operates reliably when a nut and lens holder, which has abutted on a stopper and stopped, are driven in a reverse direction.
SOLUTION: The optical pickup has first and second thrust bearings of a motor rotation shaft, the lens holder that moves in a thrust direction by the motor rotation shaft, and a pre-load section that applies a pre-load to the lens holder in the thrust direction, and is configured so that a position of the second thrust bearing can be adjusted in the thrust direction. Further, the first and second thrust bearings and the motor rotation shaft are formed with conductors. The optical pickup is manufactured by moving the second thrust bearing in a direction to approach the motor rotation shaft until conductivity between the first thrust bearing and the second thrust bearing is obtained using a conductivity checker, then moving the second thrust bearing in a direction to move away from the motor rotation shaft, and fixing the second thrust bearing to a base.
