Abstract
A magnetic head assembly comprising a deflectable piezo-electric member, such as a bi-morph leaf assembly, adapted for deflection in response to a voltage applied thereto, a magnetic head mounted on one end of the piezo-electric member and a U-shaped holder for the piezo-electric member. The U-shaped holder is formed of resilient material and has a pair of legs whose free ends are spring biased toward each other. The end of the piezo-electric member which is remote from the magnetic head is positioned between and clamped by the spring biased free ends of the legs of the holder. In one embodiment, a voltage is supplied to the piezo-electric member by a pair of plates, each formed of insulating material, with the clamped end of the piezo-electric member sandwiched between these plates, and with conducting member provided on at least one of the plates and in electrical contact with the piezo-electric member.
