The invention relates to a disk drive unit for use in a device for reading and/or writing data on a disk. It comprises a housing ( 2, 5, 6 ) which accommodates a disk drive ( 3, 8 - 12, 14 - 17 ) and a tray ( 4, 7, 13 ) for disk transport into and from the housing ( 2, 5, 6 ). The tray ( 4, 7, 13 ) is movable through an opening ( 5 ) in a wall ( 6 ) of the housing ( 2, 5, 6 ) between an opened position and a closed position. The disk drive ( 3, 8 - 12, 14 - 17 ) comprises a turntable ( 8 - 10 ) to rotate the disk around a turntable axis ( 10 ) and a pickup unit ( 11 ), which is mounted to a sledge ( 11, 12, 14 ). The sledge ( 11, 12, 14 ) is movable within an opening ( 13 ) in the tray ( 4, 7, 13 ) substantially in radial direction with respect to the turntable axis ( 10 ) so as to allow the pickup unit ( 11 ) to read and/or write data on the disk. An air flow guide element ( 14 - 17 ) is engaged with the sledge ( 11, 12, 14 ) and adapted to cover at least a portion of the opening ( 13 ) in the tray ( 4, 7, 13 ), which is left next to the pickup unit ( 11 ) in the closed position of the tray ( 4, 7, 13 ), viewed in a direction parallel to the turntable axis ( 10 ). The air flow guide element reduces air flow disturbances below a rotating disk, thereby improving playability performance of the disk drive unit.
