Abstract

A method for loading hard-disc magnetic head to compensate frictional force includes setting object loading speed and current parameter value by system when loading command is received by hard-disc magnetic head, obtaining current actual loading speed and parameter of next time according to said current parameter value, regulating loading speed of head-disc magnetic head as per current actual loading speed till hard-disc magnetic head is loaded on disc.

Description

technical field

[0001] The invention relates to the field of control, in particular to a method for loading a magnetic head of a hard disk for compensating frictional force. Background technique

[0002] When the hard disk is to be read, the magnetic head in the hard disk is loaded onto the rotating disc from the magnetic head docking station, which is a trapezoidal square. During the loading process, the head arm resting on one end of the trapezoidal square will slide from one end of the trapezoid to the upper bottom part of the trapezoid, then slide to the other end of the trapezoid, and finally fall on the rotating disc. The smoothness of the surface, the loading speed of the head arm, the material type of the trapezoidal block slope, and the airflow inside the hard disk and other factors will cause relatively large friction between the magnetic head and the trapezoidal block, and due to the friction generated during the loading process The force has nonlinear characteri...
