Patent number: 8810952Abstract: A head transducer, configured to interact with a magnetic recording medium, includes a first sensor having a temperature coefficient of resistance (TCR) and configured to produce a first sensor signal, and a second sensor having a TCR and configured to produce a second sensor signal. One of the first and second sensors is situated at or near a close point of the head transducer in relation to the magnetic recording medium, and the other of the first and second sensors spaced away from the close point. Circuitry is configured to combine the first and second sensor signals and produce a combined sensor signal indicative of one or both of a change in head-medium spacing and head-medium contact. Each of the sensors may have a TCR with the same sign (positive or negative) or each sensor may have a TCR with a different sign.Type: GrantFiled: November 17, 2011Date of Patent: August 19, 2014Assignee: Seagate Technology LLCInventors: Michael T. Johnson, Dongming Liu, Huazhou Lou, Declan Macken, Timothy W. Stoebe, James G. Wessel, Xuan Zheng

Patent number: 8737009Abstract: A temperature sensor of a head transducer measures temperature near or at the close point. The measured temperature varies in response to changes in spacing between the head transducer and a magnetic recording medium. A detector is coupled to the temperature sensor and is configured to detect a change in a DC component of the measured temperature indicative of onset of contact between the head transducer and the medium. Another head transducer configuration includes a sensor having a sensing element with a high temperature coefficient of resistance to interact with asperities of the medium. Electrically conductive leads are connected to the sensing element and have a low temperature coefficient of resistance relative to that of the sensing element, such thermally induced resistance changes in the leads have a negligible effect on a response of the sensing element to contact with the asperities.Type: GrantFiled: November 17, 2011Date of Patent: May 27, 2014Assignee: Seagate Technology LLCInventors: Gary J. Kunkel, Huazhou Lou, Declan Macken, Timothy W. Stoebe

Patent number: 6747847Abstract: A slider is used for supporting a transducing head proximate a rotating disc. The slider includes a slider body having a disc opposing face bounded by a leading edge, a trailing edge, and first and second side edges. The slider body has a longitudinal axis. An air bearing surface is defined on the disc opposing face and the air bearing surface has a pad proximate the trailing edge. A trench is positioned adjacent to the pad with the trench being recessed from the air bearing surface at a step depth. A channel for flushing lubricant from the disc opposing face is positioned on the pad. The channel is recessed from the air bearing surface at a channel depth.Type: GrantFiled: January 9, 2002Date of Patent: June 8, 2004Assignee: Seagate Technology LLCInventors: Timothy W.
