An apparatus to test the flying capability of flying magnetic heads employed by rotating, magnetic memory systems. A rotatable chuck is coupled to a vacuum system, the top surface of the chuck having apertures therein to make contact with and secure thereto a testing disk via the vacuum system. Magnetic heads aerodynamically designed to be employed over a rotating disk or drum are suspended over the surface of the testing disk. A touch detector is connected between the magnetic head and the testing disk to determine whether or not the flying magnetic head is within the designed aerodynamic specifications to operate with a given disk runout or rate of change of runout.
