Description
Technical Field
The present invention relates to a mounting device, and more particularly, to a mounting device for fixing and mounting a high-precision hard disk.
Background
The computer hard disk is the most important storage device of the computer. Hard disks (HDDs) are typically comprised of one or more aluminum or glass disks. The discs are coated with ferromagnetic material. The head is the most expensive component of the hard disk and is also the most important and critical ring of the hard disk technology. The conventional magnetic head is an electromagnetic induction type magnetic head integrating reading and writing, and the MR magnetic head, namely a magnetoresistive magnetic head, adopts a separated magnetic head structure: the write head still uses a conventional magnetic induction head, while the read head uses a new type of MR head. When the magnetic disk rotates, if the magnetic heads are kept at a position, each magnetic head draws a circular track on the surface of the magnetic disk, and the circular tracks are called tracks. Information on the disc is stored along such tracks. Adjacent tracks are not in close proximity, and the density of tracks on a hard disk is high, usually thousands of tracks on one side. The surface of the magnetic disk is coated with a magnetic medium for recording, which is microscopically represented as individual magnetic particles. If the hard disk is subjected to shock from an external force while operating at a high speed, there is a possibility that data loss will be irreparable due to the head slapping against the disk surface. In addition, the uniaxial anisotropy and volume of the magnetic particles can obviously improve the thermal stability of the magnetic particles, and the high and low thermal stability determines the stability of the state of the magnetic particles, namely the correctness and stability of the stored data.
With the development of hard disk technology, the performance of hard disks is continuously improved, high-precision hard disks are very easy to damage due to vibration and impact, the conventional hard disk fixing mode is generally that the hard disks are directly fixed by screws, and the anti-vibration effect of the fixing mode is not ideal, which is the main defect of the conventional technology.
