Abstract
A spring arm for supporting a magnetic head is formed by sticking a thin base plate to a resilience reinforcing plate. The spring arm is structured of a long and narrow base plate formed of stainless steel and a reinforcing plate stuck to the base plate. The base plate has a gimbal formed in its distal end portion. The gimbal is defined by two circular arc slits and joined with the base plate by supporting portions formed between the circular arc slits. The base plate has a sufficiently small thickness to allow the gimbal supported by the supporting portions to make a tilting movement with respect to the base plate. The circular arc slits are formed by etching the base plate.
