ABSTRACT:
Apparatus and method for enhancing the convective cooling of a voice coil motor (VCM) of a disc drive. A portion of an air flow established by the rotation of a disc of the disc drive is diverted from the disc and is directed through a channel to the VCM. In one embodiment, an air foil is provided to support first and second magnetic paths of the VCM, the air foil having a shroud surface adjacent portions of the circumference of the disc and a diverter surface angularly extending from the shroud surface, the diverter surface diverting the air to the VCM. Alternatively, a base deck of the disc drive is provided with a shroud circumferentially adjacent portions of the disc and the channel extends through the shroud to direct the air from the disc to the VCM.
