Abstract
A heat assisted magnetic recording (HAMR) write apparatus is described. The HAMR write apparatus is coupled with a laser that provides energy. The HAMR writer has a media-facing surface (MFS) and a laser-facing surface. The HAMR write apparatus includes a free-standing reflector and at least one waveguide. The free-standing reflector resides on the laser-facing surface and has a concave reflective surface oriented to receive the energy from the laser. The waveguide(s) are optically coupled with the free-standing reflector and direct energy from the laser toward the MFS.
