摘要： A perpendicular magnetic recording medium is provided. The perpendicular magnetic recording medium includes: a perpendicular magnetic recording layer formed on a substrate; and at least one soft magnetic under-layer formed between the substrate and the perpendicular magnetic recording layer, wherein the soft magnetic under-layer is made from an alloy of a non-magnetic material and a magnetic material which exists in the form of granular nanoparticles in matrix of the non-magnetic material, and at least two of the magnetic nanoparticles are spaced apart from one another by a predetermined distance so as to mutually make an anti-ferromagnetic coupling.

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 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. 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.
摘要翻译：公开了一种用于热辅助磁盘记录介质的用于硬盘的头部万向节组件，其中应用激光二极管以高密度记录信息，以及组装这种头架万向节组件的方法。用于硬盘的头部万向节组件包括：多个悬架，每个悬架设置有与磁盘中相应的盘表面相邻定位的磁头，以便记录/再现信息; 具有中心形成的枢转孔的头部万向架主体，其允许头部万向架主体以相对于盘可旋转的方式安装，悬架从头部万向架主体的一端延伸; 线圈旋转器，设置在头部万向架主体的另一端，以使头部万向节主体围绕枢转孔旋转; 以及具有一个或多个激光二极管和一个或多个波导的激光组件，从任何激光二极管发出的光被波导引导到相应的磁头。根据本发明，由于具有用于增加磁盘的数据记录密度的激光二极管的头部万向节组件不固定到悬架上，而是固定到用作头部万向节组件的支撑件的头部万向节主体，可以有效地降低从头部万向节组件产生的热量。此外，由于悬架的周边光学部件的数量减少，所以可以平稳地执行磁头的飞行，从而可以有效地执行高密度数据的记录/再现。
