A test fixture for assembling and electrical testing of 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.
