Abstract
A head suspension assembly for a disk drive that inhibits thermal pole tip protrusion includes a slider assembly having a slider exterior surface including a trailing surface, a slider interior region that is defined by the slider exterior surface, and a write head having an electrically coupled write coil positioned within the slider interior region. The write coil generates heat during write operations of the disk drive. The slider assembly also includes a heat dissipater positioned substantially within the slider interior region. The heat dissipater is electrically isolated from the write coil, and has a thermal conductivity of at least approximately 50 W/mK.
