US Patent 7467479 Headstack locator assembly for testing magnetic heads

A headstack locator assembly for locating and fixing a headstack on a spinstand and which mitigates the aforementioned prior art limitations. The headstack locator assembly includes a headstack locator received on a fixed locator. The headstack locator connects to a headstack, while the fixed locator is permanently secured to a spinstand. A vacuum is used to clamp the headstack locator to the fixed locator for testing of the headstack. Upon test completion, the headstack locator is released from the fixed locator by applying positive air pressure to the assembly.
