Abstract: PROBLEM TO BE SOLVED: To prevent a lens main body part from being floated up and displaced, when a long wraparound resin lens is provided. SOLUTION: In a lens main body part 28, a curved part 28B with a relatively small radius of curvature with respect to its longitudinal direction is formed to have a thinner wall than a flat part 28A. A middle thick-walled part 28C is provided at the boundary between the flat part 28A and the curved part 28B. A resin lens 12 has its lens main body part 28 hardened inside a metallic mold after injection, after an outer peripheral flange part 30 is hardened, and because in that case the lens main body part 28 is hardened in such a way that the relatively thick-walled flat part 28A is hardened after the relatively thin-walled curved part 28B is hardened, the amount of longitudinal compressed deformation of the curved part 28B due to the contracting action of the resin during hardening is small enough to prevent deformation in the direction in which its radius of curvature is increased.  Also, the strength of the resin lens 12 is enhanced by the intervention of the middle thick-walled part 28C.

IPC: G11B7/085
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To provide an optical disk device capable of stably setting a final target speed and shortening a time required for moving to a target track. SOLUTION: A target speed generating means 14 is controlled so as to output the target speed of an optical head 4 in order to set a target speed just before a target track becomes a lower value than a final target speed at the time of reaching the target track by using a signal generated by the fact that an optical spot crosses the track of an optical disk 1. The target speed outputted from the target speed generating means 14 and the actual moving speed of the optical head 4 detected by a speed detecting means 15 are introduced to a linear actuator driving control circuit 17 and the speed of the optical head 4 is controlled. Consequently, the deviation of speed is absorbed even in the vicinity of the target track position while keeping large decelerating force as it is and the final target speed is quickly set.  Since the high target speed is kept up to the vicinity of the target track position, the moving time to the target track is shortened.
