An actuator arm assembly for a disk drive includes first and second stamped actuator arms including first and second arm portions, first and second body portions defining first and second body surfaces, and first and second coil-supporting arm portions defining first and second pairs of coil support
An actuator arm assembly for a disk drive includes first and second stamped actuator arms including first and second arm portions, first and second body portions defining first and second body surfaces, and first and second coil-supporting arm portions defining first and second pairs of coil supporting arms for supporting a coil portion of a voice coil motor. When the first and second stamped actuator arms are attached to one another, the first pair of coil supporting arms faces and is in contact with the second pair of coil supporting arms to define first and second coil attachment surfaces, and the first body surface faces and is in contact with the second body surface to define a third coil attachment surface.

What is claimed is: 1. An actuator arm assembly for a disk drive, comprising: a first actuator arm, the first actuator arm including a first arm portion, a first body portion defining a first body surface, the first actuator arm further including a first coil-supporting arm portion defining a first
What is claimed is: 1. An actuator arm assembly for a disk drive, comprising: a first actuator arm, the first actuator arm including a first arm portion, a first body portion defining a first body surface, the first actuator arm further including a first coil-supporting arm portion defining a first pair of coil supporting arms for supporting a coil of a voice coil motor; a second actuator arm, the second actuator arm including a second arm portion, a second body portion defining a second body surface, the second actuator arm further including a second coil-supporting arm portion defining a second pair of coil supporting arms for supporting the coil of the voice coil motor, the second pair of coil supporting arms facing the first pair of coil supporting arms to define first and second coil attachment surfaces, the first body surface facing the second body surface to define a third coil attachment surface, and a first layer of adhesive disposed between the first and second pairs of coil supporting arms to attach the first and second actuator arms together. 2. The actuator arm assembly of claim 1, wherein the coil is attached to the actuator arm assembly by a second layer of adhesive between the first coil attachment surface and the coil, by a third layer of adhesive between the second coil attachment surface and the coil and by a fourth layer of adhesive between the third coil attachment surface and the coil. 3. The actuator arm assembly of claim 1, wherein the first actuator arm defines a first surface that defines a first through bore, the second actuator arm defines a second surface that defines a second through bore. 4. The actuator arm assembly of claim 3, further comprising a collar, the collar being fitted within the first and second through bores. 5. The actuator arm assembly of claim 1, further including a fifth layer of adhesive disposed between the first and second body surfaces. 6. A disk drive, comprising: a disk; a head stack assembly for reading and writing to the disk, the head stack assembly including an actuator arm assembly that comprises: a first actuator arm, the first actuator arm including a first arm portion, a first body portion defining a first body surface, the first actuator arm further including a first coil-supporting arm portion defining a first pair of coil supporting arms for supporting a coil of a voice coil motor, a second actuator arm, the second actuator arm including a second arm portion, a second body portion defining a second body surface, the second actuator arm further including a second coil-supporting arm portion defining a second pair of coil supporting arms for supporting the coil of the voice coil motor, the second pair of coil supporting arms facing the first pair of coil supporting arms to define first and second coil attachment surfaces, the first body surface facing the second body surface to define a third coil attachment surface, and a first layer of adhesive disposed between the first and second pairs of coil supporting arms to attach the first and second actuator arms together; a first head gimbal assembly coupled to the actuator arm assembly, and a coil portion attached to the first, second and third coil attachment surfaces. 7. The disk drive of claim 6, wherein the coil portion is attached to the actuator arm assembly by a second layer of adhesive between the first coil attachment surface and the coil portion, by a third layer of adhesive between the second coil attachment surface and the coil portion and by a fourth layer of adhesive between the third coil attachment surface and the coil portion. 8. The disk drive of claim 6, further including a second head gimbal assembly coupled to the second actuator arm portion. 9. The disk drive of claim 6, wherein the first actuator arm defines a first surface that defines a first through bore and the second actuator arm defines a second surface that defines a second through bore. 10. The disk drive of claim 9, further comprising a collar, the collar being fitted within the first and second through bores. 11. The disk drive of claim 6, further including a sixth layer of adhesive disposed between the first and second body surfaces.
