Method and system of testing slider body of thermally-assisted magnetic head

A method of testing dynamic performance for a slider body of a thermally-assisted magnetic head, the method comprising:

• providing the slider body, the slider body being disconnected with a light source unit and including a thermally-assisted magnetic head section, an air bearing surface and an optical waveguide;
• removably mounting the slider body to a test head suspension assembly loaded to a dynamic testing device, the test head suspension assembly being firmly connected with a test light source unit, and the test light source unit being configured to face to an opposite surface of the air bearing surface;
• controlling the test light source unit to provide a Gaussian beam to the slider body, the Gaussian beam aligning with the optical waveguide;
• and
• testing the dynamic performance of the slider body.

• removably mounting the slider body to a test head suspension assembly loaded to a dynamic testing device;
• keeping to provide a Gaussian beam to the slider body along a direction vertical to an opposite surface of the air bearing surface, the Gaussian beam aligning with the optical waveguide;
• controlling the Gaussian beam to move synchronously with track motions of the slider body;
• and
• testing the dynamic performance of the slider body.

A method of testing dynamic performance for a slider body of a thermally-assisted magnetic head, the method comprising:

• providing the slider body and a light source unit, the light source unit being temporarily attached on an opposite surface of an air bearing surface of the slider body;
• aligning a Gaussian beam emitting from the light source unit with an optical waveguide of the slider body;
• and
• testing the dynamic performance of the slider body.
