Abstract
The present disclosure generally relates to a voice coil motor (VCM) yoke for a data storage device. The VCM yoke has a unitary body turned back on itself at opposite ends to form a “C” shape. The unitary body is electrically conductive. The body has a substantially flat inner surface upon which the coil is disposed. The unitary body also has a substantially flat top and a substantially flat bottom surface. A coil is disposed within the turns of the unitary body. The VCM yoke can be coupled to an actuator block using one or more fastening mechanisms that extend through openings in the VCM yoke.
