Abstract
An information handling system including a base, a disc rotatably attached to the base; and an actuator assembly movably attached to the base. The actuator assembly also has a main body which includes a pivoting portion, an actuator arm attached to the main body, and a yoke attached to the main body. The yoke has a roughened bonding surface. A voice coil bonded to the yoke. The bonding surface has a plurality of grooves therein. The grooves or any roughening results in a plurality of features on the bonding surface of the yoke which increases the area of the bonding surface for bonding the voice coil to the yoke of the actuator assembly. The plurality of features in the bonding surface are designed to minimize cracks or potential cracking in the yoke of the actuator assembly.
