Abstract: The present disclosure generally relates a method for removing a smear from a write head in a HAMR system. The smear can be removed by sufficiently heating the smear in an oxidative atmosphere to oxidize the smear. The material buildup that forms the smear has carbon, that when oxidized, is a gaseous product that leaves the write head with a reduced and/or eliminated smear. The heating occurs when the head is disposed in the parking location on the ramp remote from the magnetic media. Heating is possible using the same heat source for the HAMR head that is used to write data to the magnetic media.
