Shock prevention method for hard disk, hard disk and vehicle electronic device

Abstract

The invention is suitable for the field of hard disks, providing a shock prevention method for a hard disk, a hard disk and a vehicle electronic device. In the shock prevention method for a hard disk, collected acceleration data is compared with the limit value of acceleration supported by the hard disk, when the acceleration data is larger than the limit value of acceleration, the magnetic head of the hard disk returns to a start position and stops reading and writing data of the hard disk so as to prevent the magnetic head of the hard disk from beating the hard disk to form failure points and damage the hard disk.

Description

technical field [0001] The invention belongs to the field of hard disks, and in particular relates to a shockproof method for hard disks, hard disks and vehicle-mounted electronic equipment. Background technique [0002] With the continuous growth of car users, the users of vehicle electronic equipment are also increasing, and hard disks, as the main data storage tool, have been more and more widely used in vehicle electronic equipment. However, on-board electronic equipment with hard disks often encounter a problem, that is, the vibration generated during the driving process of the car will cause the hard disk head to hit the disk to form a bad point, which will damage the hard disk over time, ranging from data loss to severe. Then the entire hard disk is scrapped, which will undoubtedly cause huge losses to the user. At present, there are two main anti-vibration methods for hard disks: using rubber pads to fix hard disks for anti-vibration and using wire ropes combined wi...
