摘要： An optics support for an optical disk drive which records and reproduces optical data out of the recording surface of an optical disk through optics which includes an objective lens. The optics is supported by resilient support members which are individually assigned to a focusing and a tracking direction, so that the objective lens is movable in the two different directions relative to the recording surface of a disk. The support members assigned to the focusing direction each has a substrate configured as a thin leaf spring and a film of resin which hardened when illuminated by ultraviolet rays and is provided on one surface of the substrate. The support member assigned to the tracking direction is made up of a metal substrate having two aligned slots at the intermediate thereof, sublaminates provided on opposite surfaces of the substrate to play the role of vibration-suppressing members, and metal plates provided on the outer surfaces of the sublaminates and each having a slot at the intermediate thereof. Each sublaminate has a plate made of hard resin, and layers made of soft resin and deposited on opposite surfaces of the plate.
