Abstract
Magnetic write heads for heat-assisted magnetic recording (HAMR) are disclosed that include a laser diode having a light emitting edge or surface mounted on a slider, an optical waveguide, and a printed bonding agent disposed in an air gap between the laser diode and the slider. The printed bonding agent can be applied by ink jet printing or aerosol jet printing. Also included is a method that includes attaching a laser diode to a slider of a magnetic write head and depositing a bonding agent into the air gap using a focused stream of bonding agent. A light-emitting edge or surface of the laser diode is adjacent to an optical waveguide. The light-emitting edge or surface of the laser diode and the optical input of the waveguide define an aligned direction and an air gap extends from the light-emitting edge or surface of the laser diode in a direction perpendicular to the aligned direction. The bonding agent can be applied by ink jet printing or aerosol jet printing.
