Patent number: 8730611Abstract: A method of detecting a contact between a transducing head and a storage medium is provided. The method applies an input signal, having a select power level and known frequency, to an actuator for actuating the head. An output signal is obtained in response to the input signal. At least one signal component is extracted from the output signal at the same or a harmonic of the same known frequency as the input signal applied to the actuator. Whether the at least one extracted signal component indicates a contact between the head and the medium is determined. The power level of the applied wave pattern is increased incrementally until the extracted signal component indicates a contact between the head and the storage medium.Type: GrantFiled: February 28, 2011Date of Patent: May 20, 2014Assignee: Seagate Technology LLCInventors: Dongming Liu, Lin Zhou, Adam K. Himes, Lee C. Knippenberg, Michael T. Johnson

Patent number: 6728068Abstract: A flexible circuit for use in a head gimbal assembly having low stiffness and high robustness. The flexible interconnect circuit has interconnecting leads which connect the flexible interconnect circuit to a transduction head. To ensure the transducing head is able to follow the surface of the disc and properly read from and write to the disc, the interconnect leads are constructed with a varying width. The leads are widened at the points where breakage usually occurs and are narrowed at a middle portion to ensure the leads maintain the desired flexibility.Type: GrantFiled: August 25, 1999Date of Patent: April 27, 2004Assignee: Seagate Technology LLCInventors: Adam K. Himes, Michael S. Bowers, Paul E. Kupinski
