An actuator assembly includes a rotatable actuator arm mounted on the base of a disc drive. The actuator arm includes a metallic member seated on a non-metallic body. A proximal end of a load beam is mounted on the actuator arm and a distal end of the load beam supports a head. The actuator assembly also includes a connection between the metallic member and the load beam that secures the load beam to the actuator arm.

Load beam attachment to actuator arm

An actuator assembly is provided for a computer disc drive. The actuator assembly includes an actuator body that supports a shell head support arm and/or a shell coil yoke. The coil yoke supports the coil of the VCM. The actuator body pivots about a pivot axis and is attached to the cartridge bearing assembly disposed within an inner hollow of the actuator body. The head support arm is a shell having a core, a first surface and a second surface. The first surface of the head support arm is concave and the second surface of the head support arm is convex. The head support arm is connected to the actuator body at a proximal end. At a distal end of the head support arm, there is a flat portion with a swage hole for connection of the flexure assembly.

Actuator assembly for a disc drive having shell extensions

Method and apparatus for forming a disc drive actuator assembly. A rigid actuator arm formed of printed circuit board (PCB) material is configured for placement over a rotatable disc. A head-gimbal assembly (HGA) is provided comprising a data transducing head, a flexible suspension assembly and a conductor which is connected to the head and routed along the flexible suspension assembly. A Z-axis conductive adhesive film is used to mechanically and electrically connect the HGA with a distal end of the PCB actuator arm. The Z-axis conductive adhesive film is substantially conductive across the thickness of the film and is substantially nonconductive along the length and width of the film. In a preferred embodiment, the film establishes a grounding path to dissipate electrostatic charge in the HGA. In another embodiment, the film establishes a data signal path for the head.

An actuator arm for a disc drive data storage device has an upper outer surface in a first plane, a lower outer surface in a second plane substantially parallel to the first plane, a peripheral outer surface substantially perpendicular to the first and second planes, and a voice coil embedded within the outer surfaces of the actuator arm. The actuator arm is used in a disc drive containing one or more data storage discs and preferably has a pre-amplifier embedded within the outer surfaces of the actuator arm as well as conductors preferably between the read/write head and the pre-amplifier within the outer surfaces of the actuator arm.

Fiber reinforced laminate actuator arm for disc drives

A top cover for disc drives having a hydrodynamic motor configured to prevent contact between the top cover and the motor. Embodiments of the instant invention include a housing having a top cover and a base, at least one data storage disc, at least one head capable of reading the data storage disc and a controller. The top cover includes a plurality of coupling sites, a first indented portion, a second indented portion and a raised portion, wherein at least two coupling sites are aligned such that a substantially linear path between the coupling sites crosses the second indented portion and the raised portion.
