Abstract
A disc drive and method of making a disc drive, including a voice coil magnet assembly. The voice coil magnet assembly includes a top magnetic return plate, a bottom magnetic return plate and at least one pair of magnets affixed to at least one of the plates. The voice coil magnet assembly is pre-assembled prior to attachment to a base plate. The pre-assembled voice coil magnet assembly is then structurally coupled to the base plate at a boss or attachment point, and is done so in a rotatable manner at the boss or attachment point, such that the voice coil of an actuator assembly is sandwiched by the rotation of the pre-assembled unit about the structural attachment point or boss.
