Disc rotating direction control method and device and disc

Abstract

The embodiment of the invention discloses disc rotating direction control method and device and a disc. The disc rotating direction control method comprises the steps of: receiving a trigger signal; generating a driving pulse according to the trigger signal; and sending the driving pulse to a spindle driver so that a spindle driver can control the rotating direction of a spindle motor according to the driving pulse, wherein the spindle motor is used for driving discs to rotate. The embodiment of the invention can control the rotating direction of discs, effectively lower the disc resonance and reduce the disc vibration, thereby realizing the purpose of disc protection.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of communications, and in particular, to a disk steering control method, device, and disk. Background technique [0002] A hard disk is one of the main storage media of a computer. It consists of at least one aluminum or glass disc covered with a ferromagnetic material, so the hard disk can also be called a magnetic disk. The vast majority of hard drives are fixed drives, which are permanently sealed into the hard drive. The hard disk technology develops rapidly, the capacity of the hard disk is constantly expanding, and the interface types of the hard disk are becoming more and more abundant, including Serial Advanced Technology Attachment (SATA) interface, Fiber Channel (Fiber Channel; hereinafter: FC) interface and Serial Attached Small Computer System Interface (Serial Attached Small Computer System Interface; hereinafter referred to as: SAS) interface and other types; and the size...

Problems solved by technology

However, the rotation direction of the hard disk (disk) is specific and cannot be controlled and adjusted; the existing technology changes the direction of the disk by changing the physical position of the disk

[0003] In the process of realizing the present invention, the inventors found that in the prior art, in the application scenarios containing a large number of disks, such as disk arrays, it is generally not allowed to change the physical position of the disks at will, resulting in the same steering of a large number of disks in the storage system. The reason is that the final vibration intensity of the entire disk array will be far greater than the direct accumulation of the vibration intensity of a single disk
