ABSTRACT:
An improved voice coil actuator for a head arm assembly. The portions of the voice coil which do not pass between the permanent magnets, and thus form a return path for the current, are bent substantially perpendicular to the remainder of the coil. One of these perpendicular portions is fixed to the head arm assembly by bonding or otherwise. The perpendicular arrangement of the return portion of the coil does not effect the coil's performance because this portion does not pass between the permanent magnets and thus is not involved in generating the force which moves the head arm assembly. Such an arrangement causes the voice coil to take up less room, allowing it to be placed closer the edge of the disk drive housing.
