Abstract
A thermally assisted magnetic write head includes a waveguide having a first end surface included in an air bearing surface; a magnetic pole having a second end surface included in the air bearing surface; a plasmon generator having a third end surface included in the air bearing surface; a first protective film directly covering a part of the second end surface of the magnetic pole at least; and a second protective film directly covering the first end surface of the waveguide and the third end surface of the plasmon generator. The configuration can reduce recording density and improve thermal stability, furthermore increase the producing yield.
