The invention provides a disc drive apparatus which is suitable for making the apparatus compact, light and thin and make it possible to automatically mount and discharge the disc. The disc drive apparatus has pick-up means and transfer means, and the transfer means has medium driving means, synchronous driving means and positioning means which is brought into contact with an outer peripheral edge of the disc. Accordingly, the disc can be transferred in a direction of a disc surface and can be positioned by the positioning means.

Disc drive apparatus of slot loading type

A disk apparatus comprises a tray for mounting a disk thereon, a lock arm for locking the tray to a main body chassis and releasing this locking, a coil for operating the lock arm by an electromagnetic force, a coil holder for holding the coil and transmitting the electromagnetic force to the lock arm, a magnet for applying a magnetic flux necessary for the operation, a rail for holding the tray to the main body chassis and guiding an accommodation/ejection operation, a push block for pushing out the tray, a push spring for operating the push block, an eject button pushed down when the user wants to eject the tray, a detention switch for detecting the push-down of the eject button, and a controller for applying a voltage to the coil upon receiving the detection information. The entire thickness of the tray lock mechanism is composed no more than 5 mm and is accommodated in the rear internal space of the recess so that a disk apparatus reduced in the thickness in the height direction of the outer case is presented.
