Abstract
A disk drive unit advantageously prevents dust from adhering to a pickup. The disk drive unit has a housing and a tray. The tray reciprocates between a retracted position and a projected position. A first pickup and a second pickup have a spindle motor located therebetween. The tray has a first cutout and a second cutout. A cover is provided to cover the top of the second pickup in its retreated position. The cover has a cover piece, which is disposed in a front portion of the cover that is positioned on the upstream side relative to the rotational direction of a disk-shaped recording medium such that it is movable in a direction parallel to the direction in which the second pickup moves, and urged in the projecting direction.
