Abstract
An actuator arm assembly for a disk drive is disclosed. The actuator arm assembly includes at least two actuator arms, each having a corresponding suspension and read/write head. A one-piece flex cable is attached to the upper or lower surface of each of these actuator arms, and includes at least one preamp. The flex cable provides an electrical interconnection between the read/write heads of these two actuator arms and a drive electronics board. Both of these actuator arms may be detachably interconnected with a spacer via at least one snap-lock type interconnection to allow for a “no tools” assembly/disassembly of the actuator arm assembly.
