Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] figure 1 The flow of the anti-vibration method for a hard disk provided by the embodiment of the present invention is shown, and for the convenience of description, only the parts related to the embodiment of the present invention are shown.

[0023] The method comprises the steps of:

[0024] In step S101, the acceleration data generated by the vibration of the hard disk is collected;

[0025] In step S102, the acceleration data collected is converted from an analog signal to a digital signal;

[0026] In step S103, the acceleration data in the form of a digital signal is compared with t...

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...
