Actuator for use with a disk drive having a coil assembly designed to aid in heat convection from the coil of the coil assembly

摘要

Disclosed is an actuator for use with a disk drive having a coil assembly designed to aid in heat convection from the coil of the coil assembly. The actuator includes a body portion for pivotally coupling to the disk drive and an actuator arm cantilevered from the body portion for supporting a head gimbal assembly (HGA). The actuator further includes a coil assembly having a coil and a fork. The fork is cantilevered from the body portion in an opposite direction from the actuator arm and includes a pair of opposed prongs to mount the coil. At least one of the prongs of the fork includes at least two opposed fins to aid in the convection of heat from the coil.
