Abstract

The invention relates to the technical field of magnetic head detection, and provides a magnetic head test tool suitable for various types of magnetic heads. The device comprises a frame, an upper supporting plate and a lower supporting plate are arranged at the left end and the right end of the frame, a screw is rotated to enable a magnetic strip plate to slide up and down on a sliding rod, multiple sets of magnetic strips adhere to the upper end face of the magnetic strip plate, a vertical plate is arranged in the frame, and a set of rollers are rotationally connected between the vertical plate and the frame; each set of rollers is in transmission connection with a conveyor belt; a sliding plate is placed between the conveying belts on the front side and the rear side, a magnetic head groove hole is formed in the middle of the sliding plate, the magnetic head groove hole, the frame and the concentric-square-shaped baffle jointly form a groove, a magnetic head is placed in the groove,and a connector bar is arranged on one side of the sliding plate and electrically connected with the magnetic head. And meanwhile, the connector bar is electrically connected with control equipment capable of displaying read information of the magnetic head. The magnetic head testing tool is suitable for performance testing of magnetic heads of different specifications and different types, the universality of the magnetic head testing tool is improved, and the performance stability and the performance limit of the magnetic head can be tested.

Description

technical field [0001] The invention relates to the technical field of magnetic head detection, in particular to a magnetic head testing tool suitable for various types of magnetic heads. Background technique [0002] The magnetic head is a component that reads data on magnetic media through magnetic principles. Common magnetic heads include hard disk heads, tape recorder heads, POS machine heads, and banknote detector heads. After the magnetic head is assembled, it needs to be tested before it can be used. Otherwise, it will cause a quality accident if there is a problem with the magnetic head when it is used in the terminal. Existing magnetic head tests mainly include noise testing and performance testing. Among them, the performance test mainly tests the reading sensitivity and accuracy of the magnetic head. In order to test the performance of the magnetic head, the actual application scenario of the magnetic head is generally simulated for testing. However, this test...
