摘要
A laser, such as a horizontal cavity surface emitting laser, with internal polarization rotation may be used in thermally assisted recording in hard disk drives. The desired polarization of the laser may be accomplished with two beam reflections off of facets within the laser. The facets may be formed in a single ion beam etching step. The laser may be used on a thermally assisted recording head to produce a polarized beam that is aligned with a track direction of the disk.
