摘要： 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.

摘要： A lapping method of a MAMR head slider includes a first lapping process: controlling the lapping plate to spin at a first speed, and controlling the MAMR head slider to move at a first moving speed, and applying a first force to the MAMR head slider; and a second lapping process: controlling the lapping plate to spin at a second speed that is lower than the first speed, and controlling the MAMR head slider to move at a second moving speed that is lower than the first moving speed, and applying a second force that is lower than the first force to the MAMR head slider; and the second lapping process includes a final lapping process section, and the second force in the final lapping process being zero. In such a way, lapping marks on the ABS are reduced to improve the roughness and the reliability.
