Abstract
A head actuator mechanism and a method of manufacture for that mechanism are disclosed. The head actuator mechanism includes a head gimbal assembly coupled to the top support face of a bearing assembly and an actuator driving mechanism coupled to the opposite support face. The head gimbal assembly includes an actuator arm and a load beam, the actuator arm being mounted to the top support face. The actuator driving assembly includes a driving coil and a coil holder frame. The driving coil is positioned in a magnetic field created by a magnetic block and yoke.
