Abstract

An actuator assembly for magnetic heads used with fixed magnetic discs. The heads are supported from one end of arms in a support assembly which is pivoted at the other end. Drive forces are applied directly to each of the arms through the support assembly at the center of percussion between the pivot and the heads. Drive forces are generated by a drive assembly including a coil and permanent magnets.
