Lichtafgiftemodule en warmteondersteunde magnetische opnamekop die deze gebruikt.

摘要

A light delivery module having a structure in which components can be precisely aligned and be integrated as a single unit, and a heat-assisted magnetic recording (HAMR) head employing the light delivery module. The light delivery module includes: a base having a first groove; a light source mounted on the base; an optical device that is installed on the base and guides light radiated from the light source; a cover member that is bonded to the base to protect the light source and the optical device and has a second groove facing the first groove; and a nano aperture bonded in the first and second grooves to form an enhanced near-field by adjusting the distribution of the light transmitted through the optical device.
