Abstract

The invention discloses a magnetic sensitivity detection device of a thin-film induction magnetic head, which comprises a fixed isolation mechanism, a magnetichead clamping mechanism and a displacement detection mechanism, wherein the magnetic head clamping mechanism and the displacement detection mechanism are both fixedly installed in the fixed isolation mechanism. During detection, a sound equipment power supply is turned on to generate sound such that a magnetic head fixed to a clamping piece vibrates under the impact of sound waves, thereby simulating and reproducing the vibration state of the magnetic head of a tape recorder in operation, and the displacement of the magnetic head is monitored by a laser displacement sensor mounted at the same height as the magnetic head. Further, theinvention further discloses an implementation method of the magnetic sensitivity detection device of the thin-film induction magnetic head. The clamping piece and the laser displacement sensor at thetwo ends of a connecting rod can move at the same time only by pulling up or down the connecting rod without separately adjusting the clamping piece and the laser displacement sensor to the scale lines at the same height, thereby realizing the effect of simultaneous adjustment, lower errors, and more convenience.

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...
