Abstract

Embodiments described herein generally relate to controlling the flying height of a slider. The methods can include transmitting radiation from a radiation source, determining a change in temperature, the change in temperature being the difference between a first temperature and an ambient temperature and changing the flying height of the slider and head based on the change in temperature. The devices generally include a head with a supporting surface and a media facing surface, a radiation source submount, a radiation source, and a temperature sensor positioned proximate the radiation source submount or the radiation source.
