Abstract

The disclosed suspension assembly (S) for carrying a magnetic recording head in close following relation to a recording disc includes an improved arrangement for supplying a load to the recording head. The suspension assembly (S) includes a flexible gimbal section (10a) for mounting the recording head and accommodating dampened pitch, roll and transverse movements. The head load arrangement comprises a flexible cantilevered spring tongue (10b) and an elongate rigid load member (20) that extends from the free end of the spring tongue to contact the suspension assembly (S) adjacent the recording head. The load member (20) is configured to cause the spring tongue (10b) to resiliently deflect by a predetermined amount, resulting in a predetermined head load being supplied through the load member to the recording head.
