Abstract
A thermally assisted magnetic recording head and a thermally assisted magnetic recording disk drive are disclosed. The thermally assisted magnetic recording head includes a slider body, a laser substrate, a laser and a magnetic head, wherein the laser substrate is provided on the slider body, the laser is provided on the laser substrate, and the magnetic head is provided at a front end of the slider body. The magnetic head includes an optical waveguide facing the laser. The angle between a light incident surface of the optical waveguide and an incident direction of a laser light incident on the optical waveguide is less than 90 degrees. The thermally assisted magnetic recording disk drive includes a plurality of magnetic disks and a magnetic head suspending frame. A front end of the magnetic head suspending frame is provided with the thermally assisted magnetic recording heads mentioned above.
