A disk recording-reproducing apparatus ensures a large transport distance of a tray which moves a disk-shaped recording medium between an ejecting position and a recording-reproducing position while decreasing a dimension in the transport direction. A drive section () is built into a tray () which can be extracted from and retracted into an external chassis () and moves a disk-shaped recording medium between the ejecting position and the recording-reproducing position. A pinion () comprises an output end of the drive section () and rolls on a rack () of a chucking slider () to self-propel the tray (). After the tray () completely moves to the recording-reproducing apparatus side, an output from the drive section () of the tray () is used to move the chucking slider () to the ejecting direction of the tray (). Then, a cam groove () provided on the chucking slider () is used to raise a base unit ().

Disc type recording/reproduction device

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.
