Abstract

The invention discloses a manufacturing method of a magnetic storage apparatus. The method comprises the following steps of growing a grapheme layer on a substrate; taking a heat-release tape layer as a support carrier and bonding the substrate with the grapheme layer and the heat-release tape layer; eroding to remove the substrate; obtaining the heat-release tape layer with the grapheme layer; bonding the heat-release tape layer with the grapheme layer with a smooth magnetic dielectric material layer; using a roll shaft to roll the heat-release tape layer so that the grapheme layer is separated from the heat-release tape layer and is bonded with the magnetic dielectric material layer. In the method of the invention, the grapheme is used to replace diamond-like graphite carbon in an original magnetic storage apparatus so that a flight height of a magnetic head is effectively reduced and a magnetic storage density is improved through increasing a signal to noise ratio when the magnetic head reads and writes. Simultaneously, through using the grapheme layer, collision and abrasion of the magnetic head to the magnetic dielectric material are reduced; a good anti-corrosion effect to the magnetic dielectric material is achieved and stability of a disk is increased.

Description

technical field [0001] The invention relates to storage technology, in particular to a preparation method of a magnetic storage device. Background technique [0002] With the advent of the "big data era", all kinds of information have shown explosive growth, and the preservation, retrieval, and statistical analysis of information have become the most important issues in network applications. At the same time, magnetic storage technology is also developing continuously. At present, the storage capacity of magnetic disk has reached an astonishing 500Gb / in 2 , but it still cannot meet people's demand for magnetic storage capacity, and it is necessary to continuously increase the storage density of magnetic disks. [0003] Magnetic storage hard disks access data through the interaction between the magnetic head and the magnetic medium on the surface of the disk. In the process of accessing data, the magnetic head is suspended at a certain height on the surface of the disk, and...
