A demagnetizer for magnetic heads of floppy disc drive is made up of a receiving case having a size and shape similar to those of a conventional floppy disc and of a demagnetizing member disposed at a position in the receiving case where the magnetic heads make contact with the receiving case. The magnetizing member may be mounted on a rotating disc disposed in the receiving case. The magnetism of the magnetized magnetic heads is successfully removed by such a deed that a simple action initiated by the floppy disc drive serves to actuate the magnetized magnetic heads and/or the demagnetizing member to move close together and apart from each other in an alternated way, thereby resulting in a demagnetization of the magnetized magnetic heads.
