Abstract
An integrated heat-assisted magnetic recording (HAMR) device comprises a slider that has a top surface, a bottom surface, and a trailing end. A waveguide is carried on the trailing end and a near field transducer is positioned to receive energy from the waveguide and produce plasmons for heating a region of a magnetic medium. A write pole is carried by the slider adjacent to the near field transducer. A laser is mounted on the top surface of the slider and produces a laser beam that passes through a beam shaper mounted on the top surface of the slider that collimates or focuses the laser beam. A mirror is mounted on the slider for directing the collimated or focused light beam into the waveguide.
