A method (1000) to automatically detect and rectify a tray block in a disk drive (100) is disclosed. The method comprises detecting an occurrence of a tray block in a disk drive (100) upon receiving a tray-out command or a tray-in command by determining whether the tray (108) is in an intermediate position for a predetermined time period, the intermediate 5 position being a position between a first position within a casing of the disk drive (100) and a second position projecting completely outwards from the casing, the tray arranged to receive a record carrier (110) when in the second position and being supported for movement between the first position and the second position. The detected tray block is rectified by cleaning a brush-commutator interface of a tray motor (102), the tray motor being arranged to 10 move the tray (108) between the first position and the second position. The technique is useful for CD, DVD and BD recorders and for players which have the design of tray open/close mechanism.
