Abstract: A system and method for an improved magnetic head arm assembly (HAA), reducing complexity of design and difficulty of manufacture, is disclosed.

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.

Abstract: A system and method for simplifying a head stack assembly by coupling more than one head gimbal assembly to the head arm assembly is disclosed. The head arm assembly can be an aluminum unimount assembly. The head gimbal assemblies can be loadbeam and flexible support assembly design. Each slider can be attached to a flexible printed circuitry assembly to connect the sliders to a hard drive control. The head arm assembly can act as an actuator driving section.

Abstract: A system and method for an improved magnetic head arm assembly (HAA) is disclosed. The HAA includes three principal components, a head gimbal assembly (HGA), a flexible printed circuit (FPC) assembly, and an actuator coil assembly. The design allows for HAA rigidity, yet each of the components is designable and manufacturable independent of one another, in addition to other advantages over current methods.
