To perform ejection of a disk cartridge and head loading (landing) and/or unloading (takeoff) with a single driving source and prevent damage to a disk upon head landing and takeoff. A cam protrusion which is an outputting section of a geared motor is moved at a low speed and acts upon a head lifting mechanism by which, by rotation of the geared motor in one direction (CW direction), ejection of a cartridge is performed, but by rotation in the other direction (CCW direction), landing of magnetic heads is performed for head loading of the magnetic heads.
