In order to reduce thickness of a disk drive including a traverse unit having a turntable for rotating a disk placed thereon and an optical pickup for recording and playing back the disk, and a rack-loading member disposed in a position opposite to front end of the traverse unit slidably in a left-and-right direction perpendicular to an orbit in which the disk is transported and having a cam groove formed therein in which a boss formed at the front end of the traverse unit is loosely fitted so that the traverse unit moves up or down according to the movement of the rack-loading member in the left-and-right direction, a tilted surface is formed by cutting the lower surface of a front end portion of the boss, thus thinning the boss.
