ABSTRACT:
A pair of arms to be positioned one on each side of the flexible rotating magnetic disc. Each of the arms carries a magnetic transducer means which engages the surface of the magnetic disc for the purpose of reading and/or recording data on the rotating magnetic disc. Each of the magnetic transducer means is mounted upon the support arm by a pivotal support allowing limited rotation about a single axis. The axis is displaced only slightly from the magnetic read/write head. The axes of rotation for the two heads are preferably disposed orthogonally to each other. The rotational movement of the transducer means ability is provided by a pair of balls received within pockets provided in opposed relationships between the transducer mounting means and the support arm.
