Problems solved by technology

Hard disks on general computers (especially industrial computers) cannot avoid harsh environments such as vibration, high and low temperature, and high altitude
Under these harsh conditions, not only the service life of the hard disk will be shortened, but also the daily production and life may be affected due to sudden failure.
In addition, traditional hard drives are easily damaged under impact loads such as drops, which affects data security.

Embodiment Construction

[0031] Specific embodiments of the hard disk device according to the present invention will be described in more detail below with reference to the accompanying drawings.

[0032] The present invention provides van der Waals flexible support between the magnetic head and the disk body by using the low-friction atomic-level smooth surface provided on the magnetic head and the disk body of the hard disk device, specifically, as figure 1 As shown, the hard disk device according to the embodiment of the present invention includes a magnetic head and a disk body, wherein the magnetic head and the disk body have atomically smooth surfaces with low friction. Wherein, the atomically smooth surface includes one of single-layer graphene, molybdenum disulfide, bismuth, molybdenum, and mica.

[0033] Since both the disk body and the magnetic head have atomically smooth surfaces with low friction, the van der Waals interaction between them can support the magnetic head to slide on the disk...

Abstract

The invention provides a hard disc device, comprising a magnetic head and a disc body, wherein the magnetic head and the disc body are provided with low-friction atomic scale smooth surfaces; and each low-friction atomic scale smooth surface comprises monolayer graphene, molybdenium disulfide, bismuth, molybdenum, mica and the like. Vander wale force between the low-friction atomic scale smooth surfaces is used as soft support, thus greatly reducing the distance of the magnetic head and the disc body, correspondingly improving the storage density of a magnetic disc, and being capable of realizing contact reading and writing to a hard disc. Simultaneously, due to the extreme low friction coefficient between the atomic scale smooth surfaces, the extreme high rotating speed can be easily realized, so the reading and writing speed of data of the hard disc can be improved. In addition, the hard disc device can well solve the defects of the traditional hard disc in the aspects of high-low temperature resistance, vibration resistance, shock resistance and the like, and greatly improves the stability of the hard disc.

Description

technical field [0001] The invention relates to large-capacity storage devices, in particular to a hard disk device based on a low-friction atomic-level smooth surface. Background technique [0002] The current hard disk storage has the following characteristics: the magnetic head, the disk and the moving mechanism are sealed; the surface of the fixed and high-speed rotating plated disk is flat and smooth; the magnetic head moves along the radial direction of the disk; It is in a flying state and does not directly contact the disc. The magnetic head is in contact with the disk when it stops working, but it is in a flying state when it is working. [0003] With the development of the information industry, human beings' demand for various information technologies continues to rise, such as the speed of information processing, the speed of information transmission, the speed of man-machine interface, etc. The demand will never be satisfied with the status quo. Therefore, huma...
