He has made significant contributions to the field of technology, particularly in the area of flexible circuits and transducer sliders. With a total of 10 patents to his name, Qualey's work has had a profound impact on the industry.

Latest Patents

One of Qualey's latest patents is a fixture for testing flexible circuits. This test fixture is designed for evaluating a head gimbal assembly that includes a flex circuit with multiple circuit pads before it is installed into a disc drive. The fixture consists of a contact board with several electrically conductive contact points arranged to interface with the circuit pads of the flex circuit. Additionally, it features a clamp assembly that connects to the contact board, which includes an activation end, an engagement end, and a pivot axis. The engagement end is equipped with a non-conductive surface that contacts the head gimbal assembly opposite the circuit pads.

Another significant patent involves the induced transducer head vibration. This innovation utilizes the vibration of a transducer slider during slider fly height calibration to detect contact with a disc surface. By amplifying the vibration, the transducer slider can tap the disc surface instead of dragging across it, which minimizes wear and potential damage. The amplification is achieved by applying an in-phase AC signal to the transducer slider at the same frequency as its vibration. Once the fly height is calibrated, the AC signal can be shifted out-of-phase to dampen the slider vibration.
