Abstract

The invention discloses a device and method for detecting an elastic arm. The detection device comprises a base, a linear transmission mechanism, a mounting board, a laser, an angle adjusting mechanism, a charge coupling element, a lens and a detection frame body. The laser and the charge coupling element are used for conducting three-dimensional reconstruction on the elastic arm, the posture characteristics of the elastic arm are detected, efficiency is high, stability is good, and the evaluation repeatability and reproducibility value is lowered.

Description

technical field [0001] The invention belongs to the technical field of computers and relates to a detection device and method for an elastic arm. Background technique [0002] With the rapid development of the computer hard disk industry, the track density of the hard disk becomes denser and the storage capacity becomes larger and larger. The reading method of the magnetic head in the hard disk has also undergone a qualitative leap. From the traditional magnetic head relying on the voice coil motor, driving the bearing, and driving the elastic arm to track once, it has changed to adding piezoelectric ceramics to the elastic arm to form a secondary drive system. Realize precise tracking on high-density discs. At the same time, in order to increase the access speed of the hard disk, the working speed of the hard disk is also increased accordingly. In this way, higher requirements are placed on the reliability and security of data access by the magnetic head on the high-densi...
