英文摘要	A TAMR (Thermal Assisted Magnetic Recording) write head uses the energy of optical-laser excited surface plasmons in a plasmon generator to locally heat a magnetic recording medium and reduce its coercivity and magnetic anisotropy. The optical radiation is transmitted to the plasmon generator by means of a waveguide, whose optical axis (centerline) is tilted relative to either or both the backside surface normal and ABS surface normal in order to eliminate back reflections of the optical radiation that can adversely affect the properties and performance of the laser. Variations of the disclosure include tilting the plasmon generator, the waveguide and the laser diode.
