In some embodiments, the memory cell comprises a programmable bipolar resistive sense memory element connected in series with a programmable unipolar resistive sense switching element. The memory element is programmed to a selected resistance state by application of a selected write current in a selected direction through the cell, wherein a first resistance level is programmed by passage of a write current in a first direction and wherein a second resistance level is programmed by passage of a write current in an opposing second direction. The switching element is programmed to a selected resistance level to facilitate access to the selected resistance state of the memory element.

摘要： A shock sensor comprises a substrate and at least one flexure coupled to the substrate and configured to deflect upon an application of force to the shock sensor sufficient to deflect the flexure. Deflection of the at least one flexure produces a detectable change in an electrical property of the shock sensor. Examples of detectable changes in an electrical property of the shock sensor include an open circuit condition, a closed circuit condition, and a variation in voltage of a piezo-electric detector. In some embodiments, the change in the electrical property of the shock sensor may be remotely read by interrogation of a radio frequency identification transponder positioned on the substrate using a remote radio frequency identification transceiver. The disclosure also relates to a shock sensing system and method of shock detection.

摘要： The present invention provides a magnetic writer. The magnetic writer comprises a write circuit, a write pole, a first write coil for inducing a first magnetic field in the write pole by a first current provided by the write circuit, and a second write coil for inducing a second magnetic field in the write pole by a second current provided by the write circuit. The write circuit provides a first current through the first coil and a second current through the second coil. The write circuit controls the direction of the first current and the second current so that, during writing, the first magnetic field and the second magnetic field have components perpendicular to the air bearing surface that are in the same direction. When not writing, the first magnetic field and second magnetic field have components perpendicular to the air bearing surface in opposite directions.

摘要： A magnetic transducing head having an air bearing surface has a bottom shield, a shared pole, a read element, a substantially planar composite top pole; and a conductive coil. The read element is positioned between the bottom shield and the shared pole. The top pole is formed of high magnetic moment pole tip portion and a high resistivity yoke portion. The pole tip portion of the top pole is substantially coplanar with the yoke portion of the top pole. The pole tip portion of the top pole is separated from the shared pole at the air bearing surface by a write gap, while the yoke portion of the top pole is in contact with the shared pole opposite the air bearing surface. At least a portion of the conductive coil is positioned between the shared pole and the top pole.

摘要： A system for determining a height of a sensor includes a first triangle, a second triangle, a first rectangle, and a second rectangle. The sensor is positioned in a first plane and has a lapping surface. The first triangle, the second triangle, the first rectangle, and the second rectangle are each positioned in the first plane. A first point of the first triangle is positioned below the lapping surface of the sensor and a second point and a third point of the first triangle are positioned above the lapping surface of the sensor. A first point and a second point of the second triangle are positioned below the lapping surface of the sensor and a third point of the second triangle is positioned above the lapping surface of the sensor. A first portion of the first rectangle is positioned above the lapping surface of the sensor and a second portion is positioned below the lapping surface of the sensor. The second rectangle is positioned below the lapping surface of the sensor. A second plane in which the lapping surface of the sensor is located intersects the first triangle, the second triangle, the first rectangle, and the second rectangle. The height of the sensor is calculated through use of a pre-processing height of the sensor, a pre-processing width of the first and the second triangles, and a post-processing width of the first and the second triangles.
