热辅助磁记录头及热辅助磁记录磁盘驱动器
摘要：
本发明涉及一种热辅助磁记录头及热辅助磁记录磁盘驱动器，该热辅助磁记录头包括滑块主体、激光基板、激光器和磁头，所述激光基板设置在滑块主体上，所述激光器设置在所述激光基板上，所述磁头设置在所述滑块主体的前端，所述磁头包括正对所述激光器的光波导路，所述光波导路的入光面与激光入射到所述光波导路的入射方向的夹角小于90度；该磁盘驱动器包括多个磁盘和磁头悬架，所述磁头悬架的前端设置有如以上所述的热辅助磁记录头。在本发明的热辅助磁记录头中，由于光波导路的入光面与入射方向的夹角小于90度，入光面的反射光线不会沿入射方向返回激光器，可以改善激光发射不稳定和抑制跳模。
摘要（英）：

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.
