OBJECT LENS DRIVING APPARATUS OF OPTICAL DISK

摘要

a holder of the object lens having the object lens which is connected to signal recording plate a light beam emitted from semiconductor laser of the optical disk; an actuator base 5 having a permanent magnet and a yoke of magnetic circuit; a carriage 16 having a long tilt to insert screw holder for tilt controlling and controlling into two direction; a thick adhesive section 8 for adhering the holder of the object lens; a tracking plate spring 9 fixed the edge at the body of the plate spring; a plate spring body 10 having a V groove to control V direction of the object lens tilt and a hole as circulation center in tilt control; a rubber spring 11 having circular head plate 11a and middle plate 11, and the inserting stick 12; a slide entrance 15 for U direction tilt controlling of the object lens, and established below the fixed groove 20 formed on plate to achieve the role of the yoke as flux path; and a rubber spring pin 21 for adhering at the V groove 17 the slide entrance 15 of the actuator base.
