ABSTRACT:
The magnetic head tester of the present invention drives a medium for rotation to float a slider from the medium so as to test a magnetic head for its characteristics, and the tester includes a holder removably holding the slider opposed to the surface of the medium, and suspension means provided in the holder which has the same function as a suspension supporting the slider in a real apparatus. With this tester, tests can be executed by exchanging the slider alone, and it is unnecessary to discard the suspension even when the magnetic head is judged to be defective, thus the loss of production costs for the suspension and processing costs for assembling the slider in the suspension can be avoided.
