Cleaner for the Access Arm and Magnetic Head for Magnetic Disks

A flexible brush wheel 10 disposed on rotatable shaft 12 is provided for cleaning the upper surface 16a and the lower surface 16b of access arm 16 adapted to be moved into contact with a magnetic disk, not shown.

Access arm 16 has a protruding magnetic transducer 25 on its lower surface 16b. Access arm 16 may be moved in direction A so as to move transducer 25 into a data transferring contact with respect to a magnetic disk.

A pair of collars 26 and 28 fixed on shaft 12 are used for holding flexible brush wheel 10 rotatably disposed on shaft 12 which is in a fixed vertical position. Brush wheel 10 may be of thin flexible material and carries brush fibers on both its upper and lower surfaces.

Access arm 16 is moved beneath flexible brush wheel 10 in such a position that wheel 10 is sprung upwardly, in order to clean the upper surface 16a of access arm 16. This causes the lower surface of brush wheel 10 to have frictional brushing relationship with the upper surface 16a of access arm 16. The lower surface 16b of access arm 16 and transducer 25 are cleaned similarly, by moving access arm 16 so that its lower surface 16b has a frictional brushing relationship with the upper surface of wheel 10.

Wheel 10, in its cleaning action, may rotate relative to shaft 12 and is driven by inertia or frictional forces. In this connection, shaft 12 may rotate at a considerably faster speed than the preferred speed at w...
