Beschreibung
Zusammenfassung:	A disk drive comprising a tray (TR) for receiving a disk, the tray (TR) being supported for movement between a first position within a casing (CS) of the disk drive and a second position projecting from the casing (CS), an electric motor for moving the tray (TR) between the first and second positions, and a regulation device for regulating an electric current through the motor for regulating the rotation of the motor. The regulation device comprises a detection device for detecting a back-electromotive voltage produced during rotation of the motor for deriving position information of the tray (TR) with respect to the first and second positions.
