HEAD GIMBALS ASSEMBLY OF HARD DISK AND METHOD OF ASSEMBLING THEREOF

摘要

Disclosed is 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, and a method of assembling such a head gimbals assembly. The head gimbals assembly for a hard disk comprises: 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 rotaor 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. According to the present invention, because the head gimbals assembly having a laser diode used for increasing a data recording density of a magnetic disk is not fixed to a suspension but fixed to a head gimbals body which serves as a support for the head gimbals assembly, the heat produced from the head gimbals assembly can be efficiently lowered. Furthermore, because the number of peripheral optical components of the suspension is reduced, the flight of a magnetic head can be smoothly performed, so that the recording/reproducing of high density data can be efficiently performed.
