Thermally assisted magnetic head, head gimbal assembly, and hard disk drive
A thermally assisted magnetic head is formed by performing a head forming process, a mounting part forming process and a light source mounting process in that order. In the head forming process, a planned area is secured on a light source placing surface of a slider substrate, then a magnetic head part is formed on a head area other than the planned area and a spacer for securing a mounting space for the laser diode is formed on the planned area. In the mounting part forming process, a light source mounting part is formed by removing the spacer. In the light source mounting process, a laser diode is mounted on the light source mounting part formed by the mounting part forming step.
