Abstract
A thermally assisted magnetic head (TAMH) slider having an air bearing surface and a back surface opposite the air bearing surface, which includes a slider substrate, a magnetic head portion configured on the slider substrate and having a waveguide formed therein, a semiconductor surface emitting laser configured on the back surface with an emitting surface facing the back surface; and a lens configured between the semiconductor surface emitting laser and the waveguide for focusing lights emitted from the semiconductor surface emitting laser on an incident end of the waveguide. The TAMH slider has stable performance, and can rapidly write data to a magnetic recording medium with high recording density.
