The present invention relates to a nitride-based electronic device and a method for manufacturing same, the nitride-based electronic device comprising a substrate, a metal electrode and a plurality of protection layers, wherein, among the protection layers, at least two protection layers covering one portion of the electrode so that one portion of the upper part of the electrode is exposed are configured so that the upper protection layer covers the end part of the lower protection layer so as to prevent the end part of the lower protection layer from being exposed.

Nitride-based electronic device and method for manufacturing same

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.
