Abstract
A head gimbals assembly for a hard disk for use in a thermally assisted magnetic disk recording medium, in which a laser diode is applied so as to record information with high density. The head gimbals assembly for a hard disk having a plurality of suspensions, each of which is provided with a magnetic head positioned adjacent to a corresponding disk surface among the disks so as to record/reproduce information; a head gimbals body having a centrally formed pivot hole which allows the head gimbals body to be fitted in such a manner as to be rotatable in relation to the disks, the suspensions extending from one end of the head gimbals body; a coil rotator provided at the other end of the head gimbals body so as to rotate the head gimbals body about the pivot hole; and a laser assembly having one or more laser diodes and one or more wave guides, the light emitted from any of the laser diodes is guided to a corresponding magnetic head by the wave guides.
