Abstract
A slider generally comprises a substrate forming at least part of a body of the slider, a heat-assisted media recording (HAMR) read/write transducer proximate the substrate, and an end cap substantially encapsulating the HAMR read/write transducer. The end cap has a first surface proximate the substrate and a second surface as a trailing edge of the slider. The end cap has a first coefficient of thermal expansion (CTE) similar to a corresponding CTE of the substrate. At least a portion of the second surface of the end cap has a second CTE that is lower than the first CTE. A body of the end cap is intermediate to the first and second surfaces of the end cap and has a CTE intermediate of the first and second CTE.
