A disk driving device which receives a disk cartridge accomodating an information recording disk and drives the information recording disk rotatively for recording information in and for reproducing information from the information recording disk, which comprises a holder for holding the disk cartridge received in the disk driving device, springs for biasing the holder toward a turntable for rotatively driving the information recording disk, a lever for securing the disk cartridge to the holder, a sliding plate which travels along a frame moving the disk cartridge vertically toward or away from the turntable, a spring for always biasing the sliding plate toward the disk cartridge receiving side of the device, a locking lever for restraining the sliding plate from moving toward the cartridge receiving side when the holder is raised from the turntable and located at a predetermined position near the cartridge receiving side and for releasing the sliding plate to allow the holder to move horizontally and vertically toward the turntable after the disk cartridge has been secured to the holder by the lever, and holder control lever for shifting the holder in a direction opposite the direction of movement of the sliding plate. The direction of movement of the sliding plate is inverted by the holder control lever to drive the holder, so that the position of the sliding plate and that of the holder can be regulated accurately for reliable automatic loading and ejecting operation.
