摘要： A magnetic head slider having an air bearing surface is used for reading and writing data from a magnetic medium. The magnetic head includes a substrate having a disc opposing face bounded by a leading face, a trailing face, and first and second sided edges. The slider includes an end layer positioned upon the trailing face of the substrate wherein the basecoat has a disc opposing face and is comprised of a material having a coefficient of thermal expansion greater than a coefficient of thermal expansion of the substrate. An air bearing pad is formed solely on the disc opposing face of the end layer. A transducing head is formed in the air bearing pad and exposed at an air bearing surface.

摘要： A sensor comprises a transducer portion including a semi-permanently deformable portion. A deformation of the semi-permanently deformable portion in response to an activation energy deforms the transducer portion. The deformation is retained after the activation energy is removed. In another embodiment of the invention, a transducer comprises a body having an active element, a magnetostrictive element and a magnet having a magnetic field. The magnetic field causes a deformation of the magnetostrictive portion thereby adjusting the position of the active element.

摘要： An air bearing slider includes a slider body, a head stack portion attached to a rear portion of the slider body, and a transducer contained within the head stack having a pole tip for communicating with a disc. A distance separates a plane containing the bottom surface of the pole tip and a plane containing the bottom surface of the slider body. The head stack portion includes a material that is semi-permanently deformable, and a deformation of the material changes the distance. A method for adjusting a pole tip position in an air bearing slider includes providing an air bearing slider having a material within a head stack portion. A distance separates a plane containing the bottom surface of the pole tip and a plane containing the bottom surface of the slider body. The method includes semi-permanently deforming the material to change the distance.

摘要： The magnetoresistive sensor has an MR stack and side shields formed by contacts and/or pedestals on either side of the MR stack. The materials for the contacts and pedestals are selected to be magnetically soft, electrically conductive and have a low AMR signal. The contacts and pedestals are magnetically decoupled from the hard bias materials by placement of spacers.

摘要： The magnetoresistive sensor has a bottom shield, a nonmagnetic metallic pedestal, a bottom reader gap, a biasing element, a magnetoresistive stack, current leads, a top reader gap, and a top shield. The nonmagnetic metallic pedestal is positioned on a portion of the bottom shield and the nonmagnetic metallic pedestal has a width less than the width of the bottom shield. The bottom reader gap is positioned on the nonmagnetic metallic pedestal and on the bottom shield such that a portion of the bottom reader gap over the nonmagnetic metallic pedestal is raised relative to portions of the bottom reader gap not over the nonmagnetic metallic pedestal.
