Abstract

The invention discloses a magnetic sensitivity detection device of a thin-film induction magnetic head, which comprises a fixed isolation mechanism, a magnetic head clamping mechanism and a displacement detection mechanism. Both the magnetic head clamping mechanism and the displacement detection mechanism are fixedly installed in the fixed isolation mechanism. The power of the head is turned on, and the sound makes the magnetic head fixed on the clamping part vibrate under the impact of sound waves, simulating and restoring the vibration state of the magnetic head of the tape recorder when it is working, and through the laser displacement sensor installed at the same height as the magnetic head. displacement is monitored. At the same time, the invention also discloses a method for implementing the magnetic sensitivity detection device of the thin-film induction magnetic head, which does not need to adjust the clamping piece and the laser displacement sensor on the scale line of the same height, but only needs to pull up or push down the connecting rod, The clamping parts at both ends of the connecting rod and the laser displacement sensor are moved at the same time to achieve the effect of simultaneous adjustment, and the error is smaller and more convenient.

Description

technical field [0001] The invention relates to the technical field of production and detection of a thin film induction magnetic head, in particular to a magnetic sensitivity detection device of a thin film induction magnetic head and an implementation method thereof. Background technique [0002] A thin-film disk is a hard disk storage medium that uses a thin metal alloy or glass coating instead of the carbonaceous coating found in other hard disks. It not only increases the storage density, but also is more durable. A magnetic head refers to a component that reads data on a magnetic medium through magnetic principles. Common magnetic heads include hard disk heads, tape recorder heads, etc. [0003] During the production process of the magnetic head of a magnetic tape recorder, it is necessary to detect the magnetic sensitivity of the magnetic head, and the existing magnetic sensitivity detection device cannot restore the state of the magnetic head when it is working due...
