ABSTRACT:
A recording/reproducing apparatus for a disc accommodates a magnetic disc in a disc cartridge. The disc may be loaded on a disc table of a disc rotating-driving device by the operation of introducing the disc cartridge into a cartridge holder which is supported for vertical movement along the rotational axis of the disc rotating-driving device. The magnetic head is brought into contact with the magnetic disc after loading the magnetic disc on the disc table and rotationally driving the disc rotating-driving device. Since the magnetic head is contacted with the magnetic disc after loading the disc on the disc table and setting the disc into rotation, the magnetic head and the magnetic disc may be contacted with each other after removal of dust and dirt occasionally affixed on the disc surface.
