Patent number: 8026719Abstract: A topography sensor and method include a probe configured to traverse a surface to determine a topography. A stray magnetic field is disposed in proximity to the probe. A magneto-resistive sensor is configured so that the stray magnetic field passing through it changes in accordance with positional changes of the probe as the probe tip traverses the surface.Type: GrantFiled: October 3, 2008Date of Patent: September 27, 2011Assignee: International Business Machines CorporationInventors: Peter Baechtold, Urs T. Duerig, Walter Haeberle, Armin W. Knoll, Charalampos Pozidis, Deepak Ranjan Sahoo, Gian R. Salis, Abu Sebastian

Patent number: 7848213Abstract: A storage device including a storage medium for storing data in the form of topographic or magnetic marks. At least one probe is mounted on a common frame, the common frame and the storage medium designed for moving relative to each other for creating or detecting said marks. Each probe includes a tip facing the storage medium, a read sensing element, a write element and a capacitive platform, that forms a first electrode and is designed for a voltage potential applied to it independent from a control signal for said read sensing element and for said voltage potential applied to said capacitive platform being independent from a control signal for said write heating element. It further comprises a second electrode arranged in a fixed position relative to the storage medium forming a first capacitor together wherein said first electrode and a medium between the first and second electrode.Type: GrantFiled: August 4, 2008Date of Patent: December 7, 2010Assignee: International Business Machines CorporationInventors: Peter Baechtold, Johannes G. Bednorz, Gerd K. Binnig, Giovanni Cherubini, Evangelos S. Eleftheriou, Michel Despont

Publication number: 20100116038Abstract: A method is provided for determining the topography of an object. A micro-cantilever with a scanning tip is provided. The micro-cantilever includes a thermal sensor. A biased voltage is applied across the thermal sensor. A resistance change of the thermal sensor is then identified. The bias voltage is then modulated, based on the resistance change to enhance the bandwidth and the sensitivity of the thermal sensor. Responsive to the scanning tip traversing a topographical variation on an object, the thermal sensor is vertically displaced with respect to the object, which induces a temperature change of the thermal sensor. A subsequent electrical resistance change of the thermal sensor is then identified, the subsequent electrical resistance change corresponding to a subsequent temperature change. The position of the object relative to the thermal sensor is then identified based on a difference between the initial electrical resistance and the subsequent electrical resistance.Type: ApplicationFiled: November 12, 2008Publication date: May 13, 2010Applicant: International Business Machines CorporationInventors: Peter Baechtold, Abu Sebastian, Dorothea W.

Patent number: 7173547Abstract: Methods and apparatus for compensating offsets in a read signal generated by a sensor associated with a probe of a local-probe data storage device during read-scanning by the probe of bit-positions on a storage surface. An apparatus comprises a generator for generating an offset compensation signal, and a subtraction stage for producing an output signal dependent on the difference between the offset compensation signal and the sensor read signal at each bit-position. In some embodiments, an offset signal generator generates an offset compensation signal dependent upon a predetermined measurement of the sensor read signal. In another aspect the offset signal generator low-pass filters the sensor read signal during read scanning to generate the offset compensation signal. Particular embodiments also include a secondary offset compensation stage for applying additional offset compensation techniques to the output signal from the subtraction stage.Type: GrantFiled: March 18, 2005Date of Patent: February 6, 2007Assignee: International Business Machines IncorporatedInventors: Peter Baechtold, Giovanni Cherubini, Evangelos S. Eleftherious, Theodor W. Loeliger

Patent number: 7109905Abstract: Apparatus for detecting data in a sensor signal generated by a read sensor in a local probe data storage device comprises a differentiation for subtracting a value of the sensor signal from the succeeding value of the sensor signal to generate a ternary difference signal; and a convertor connected to the differentiator for converting the difference signal into a binary output signal indicative of the detected data. A local probe data storage device comprising such apparatus is also described.Type: GrantFiled: July 19, 2002Date of Patent: September 19, 2006Assignee: International Business Machines CorporationInventors: Peter Bächtold, Gerd K.
