An optical disk player which has low production costs and prevents the generation of noise. The optical disk player includes a pick-up device for recording data on a disk or reading the data recorded on the disk and a feeding device for moving the pick-up device in a radial direction of the disk. The feeding device includes a feeding motor, a lead screw rotated by the feeding motor, and a slider. The lead screw has a spiral groove formed in the outer cylindrical surface thereof. The slider includes contact portions inserted into the spiral groove of the lead screw to convert the rotary motion of the lead screw into a rectilinear reciprocating motion and a pressure portion for preventing the contact portions from being separated from the spiral groove, thereby preventing the generation of noise.
