Description
Technical Field

Background
Hard disks are one of important accessories of computers, and currently, hard disks are mainly classified into Solid State Disks (SSDs) and mechanical hard disks (HDDs). The mechanical hard disk mainly comprises a disk, a magnetic head, a control motor, a data converter and the like. The working principle of the mechanical hard disk is that data is recorded by the polarity of specific magnetic particles, when data is read, the magnetic head converts different polarities of the magnetic particles into different electric pulse signals, then the signals are converted into data which can be read by a computer by a data converter, and the operation of writing data is opposite to the operation of writing data.
For some individuals or units engaged in works such as shooting, video processing and special effect making, a large amount of data needs to be stored for a long time, large-scale enterprises generally adopt a storage server to store the data, and small-sized studios or individuals can only store the data in a mode of operating a multi-hard-disk system. However, under the condition of the same memory, the price of the mechanical hard disk is far lower than that of the solid state hard disk, and the service life of the mechanical hard disk is longer. Therefore, the operation of multiple mechanical hard disk systems becomes the best choice for small studio or personal data storage.
The magnetic head of the mechanical hard disk can move along the radius direction of the disk, the motor drives the disk to rotate at the rotating speed of thousands of revolutions per minute, and the magnetic head can be accurately positioned at any position of the disk to carry out data reading and writing operations. In the reading and writing process, the higher the rotating speed is, the more violent the vibration of the mechanical hard disk is, and the larger the generated noise is. The existing common multi-mechanical hard disk fixing device can reduce the vibration degree of mechanical hard disks to a certain degree, but the problem of generating vibration noise when a multi-mechanical hard disk system works is reduced in real time in an effective mode.
