ABSTRACT:
A test fixture for assembling and electrical testing of a magnetic head includes a fixed baseplate, a cage, and an X-Y positioner that is adjustably mounted on the baseplate. The cage is formed of a flat, thin, elongated arm and is secured at its rear end to the X-Y positioner. The forward end of the cage extends into a notched section that surrounds part of the slider. A stationary mounting block supports and retains the suspension in a fixed position relative to the slider. In another embodiment, the rear end of the cage is secured to the stationary mounting block and the X-Y positioner supports the suspension. The testing method includes pre-wiring a slider and separately mounting the wired slider and suspension into the test fixture. Adhesive is applied on the slider or suspension for establishing a temporary bond between the slider and the suspension. The suspension is then loaded onto and temporarily positioned relative to the slider. A magnetic disk is rotated over the slider, and the generated dynamic performance is analyzed. If the dynamic performance is not adequate, then the position of the slider is adjusted relative to the suspension.
