ABSTRACT:
A suspension is provided for supporting a magnetic transducing head with respect to a carriage, for movement with the carriage and relative to a substantially planar magnetic recording surface. Two parallel and spaced apart flexure arms extend from the carriage, and are extremely thin in the dimension perpendicular to the recording surface. The remote ends of the flexure arms are joined by an elongate rigid cross-bar directed transversely of the arms. The transducing head is fixed to the cross-bar, intermediate the flexure arms. When the recording surface is moved, an air bearing between the recording surface and head stabilizes the head, and the flexure arms are constrained to behave as elastic beams fixed at both ends. In particular, the flexure arms are subject to lengthwise torsional bending, and pure bending about axes parallel to the cross-bar, enabling the head/cross-bar assembly to respond in gimbal fashion to recording surface irregularities.
