Summary:A magnetic head loading/unloading apparatus has a head arm being maintained in either a loading state or an unloaded state by means of a permanent magnet. The head arm has a magnetic head on one end thereof, and is fixed on an end of a first yoke. A second yoke is arranged parallel to the first yoke, and is rotatable on the first yoke. A touching member is fixed on the second yoke, the touching member pressing a bottom surface of the head arm so as to elastically deform the head arm so that the magnetic head is positioned in an unload position. A permanent magnet is provided on the first yoke and a coil is provided on the second yoke. When the second yoke is moved to a first position, the head arm is elastically bent by a pressing force exerted by the contacting member so that the magnetic head is positioned in an unload position. When the second yoke is moved to a second position, the contacting member is apart from the head arm so that the magnetic head is in a load position. The second yoke is maintained in either the first position or the second position by the attracting force generated by the permanent magnet.
