ABSTRACT:
A tray carrying-in starting mechanism for a disk drive is simple and reduces a load at the start of carrying-in of the tray. The tray carrying-in action is started by pushing a tray that has been carried out to a disk exchange position. The starting mechanism comprises a projection provided on a rear end portion of a rack with a predetermined spacing from a tooth at a rear end of the rack. An untoothed portion is provided on an outer periphery of the gear that meshes with the rack, and a cam groove is formed on the outer periphery of the gear to allow the projection to slide over a predetermined extent and to engage therewith. The projection engages with the cam groove when the tray is carried out to the disk exchange position, and the tray can be retracted a predetermined distance without rotation of the gear when the tray is pushed.
