Problems solved by technology

[0005] The purpose of the present invention is to provide a positioning method and a positioning mechanism for the magnetic head to go down to the working position, mainly to solve the technical problem that the magnetic head in the existing device is easy to collide with the magnetic medium when it is descending, causing the magnetic head to be damaged. This method and mechanism can Greatly reduce the chance of damage to the magnetic head and prolong the service life of the magnetic reading device

Abstract

The invention relates to a locating technology for a magnetic head with a magnetic reading device, in particular to a locating method and a locating mechanism for the magnetic head to move down to a working position. The method comprises the steps: when the magnetic head is driven by a down electrical motor to move down to the working position, firstly a locating framework is pushed below the magnetic head which still moves down continuously; and when the working position is reached, the locating framework is withdrawn upwards, the magnetic head is exposed and simultaneously the down electrical motor is stopped to move down. The invention mainly resolves the technology problem: in the existing devices, the magnetic head strikes magnetic medium easily when moving down, thus damaging the magnetic head. The method and the mechanism can lower the probability of damaging the magnetic head greatly and prolong the service life of the magnetic reading device.

Description

technical field [0001] The invention relates to a magnetic head positioning technology with a magnetic reading device, in particular to a positioning method and a positioning mechanism for a magnetic head descending to a working position. Background technique [0002] As we all know, the magnetic head is an important part of the magnetic reading device (such as: computer hard disk), once the magnetic head is damaged, the entire magnetic reading device will be scrapped. Therefore, no matter in design or in use, some schemes and structures for protecting the magnetic head need to be provided. In actual use, the damage of the magnetic head is mainly caused by two reasons: [0003] 1. The magnetic head is damaged after excessive use or long-term use. This situation is almost unavoidable, and people can only further prolong the service life of the magnetic head through reasonable usage habits and scientific equipment maintenance methods. [0004] 2. The magnetic head collides ...
