MAGNETIC HEAD OF READ/WRITE CONTACT HARD DISK DRIVE, HARD DISK DRIVE DEVICE AND TRANSFER METHOD

摘要

Provided is contact technology of the magnetic head sliding block of a read/write contact hard disk drive (HDD) and a disk body. The contact surface of the magnetic head sliding block contacting the disk body is provided with at least one layer of two-dimensional atomic crystals having a planar structure and extending to the side surface of the magnetic head sliding block; the disk body has atom-scale smoothness, and the contact surface contacting the magnetic head sliding block is at least one layer of two-dimensional atomic crystals or diamond-like carbon (DLC) nanometer film. When reading data, the magnetic head sliding block and the disk body always maintain atomic contact. The two-layer structure of the directly contacted two-dimensional atomic crystals between the magnetic head sliding block and the disk body of the present invention has non-coplanarity, and is in a super-lubricated state, that is, the friction between the magnetic head sliding block and the disk body is nearly zero. The magnetic head sliding block is in atomic contact with the disk body, thus greatly reducing the distance between the magnetic head sliding block and the disk body; in addition, a DLC protective layer in a traditional magnetic head sliding block can be completely eliminated, thus further reducing the distance between the magnetic head sliding block and the disk body, and realizing higher storage density, faster storage and reading speed and a smaller HDD device.
