An objective lens actuator includes a magnetic member and magnet. The optical pickup may become contaminated by uncured adhesive remaining at the edges of the adhesive surfaces of the magnet and the magnetic member that is transferred to the optical pickup via finger cots or tweezers, etc. In an adhesion step between the magnet and the magnetic member, in which part of a groove near to the center of the surface has a small depth and part of the groove near to the outer circumference of the surface has a large depth, an adhesive is drawn toward the center of the surface of the magnetic member by a capillary phenomenon and is prevented from spreading along the outer edge of the surface. | 04-04-2013 |

A disk drive device has a casing and a disk tray on which the spindle motor and the pickup are mounted; and a pair of parallel first and second guide mechanisms that slidably supports the disk tray so as to eject the disk tray from the casing to the outside. In the disk drive device, in a center part in a width direction along the disk mount surface of an introduction side distal end part of the disk tray, an introduction side abutment part having a groove section or a protruding portion is formed, and an inner part abutment part formed on an elastic member is installed on an inner side inner wall part. | 05-30-2013 |
20130223202 | OPTICAL PICKUP - In a photo-detector position adjustment/bonding process, it has been necessary for a worker to hold a dangling photo-detector and plate with a tool such as tweezers, and chuck the photo-detector and plate onto an adjustment jig. Because the chucking onto the adjustment jig is performed by a manual operation, productivity is low and it has been difficult to decrease the process standard time (ST). In order to substantially stabilize the standby position of the photo-detector, a pressing force is provided by the reaction force of a flexible substrate in the direction of an optical pickup, and the contacting surfaces of an optical pickup case and the plate are prevented from sliding and displaced from each other. | 08-29-2013 |
