摘要： A thin film magnetic recording playback head is disclosed wherein mechanically coupled films of a magnetostrictive material and of a piezoresistive material are utilized with a solid state amplifier electrically coupled to sense resistance changes in the piezoresistive film. In operation, localized magnetic patterns on a recording medium induce strain in the magnetostrictive film, which in turn induces in the piezoresistive film corresponding changes in electrical resistance.

摘要： A thin-film magnetic recording playback head is disclosed wherein mechanically coupled films of a magnetostrictive material and of a piezoelectric material are deposited on a substrate together with a solid state amplifier which is coupled to the piezoelectric film. In operation, localized magnetic patterns on a recording medium induce stress in the magnetostrictive film, which in turn induces in the piezoelectric film a corresponding electrical polarization of non-equilibrium charge density, having a potential associated therewith which is applied to the solid state amplifier.

摘要： An Electronic Article Surveillance (EAS) marker is adapted for direct application to optically recorded media such as compact disks, CD-ROM's, laser disks, digital video disks, and the like. The marker includes a support sheet and one or more marker elements which are positioned such that the mass distribution of the marker is symmetrically disposed about the center of the marker. This ensures that when the marker is properly positioned on the optically recorded media, the marker does not adversely affect the mechanical balance of the media.

摘要： A method for manufacturing a nonlinear, dual-axis thin-film magnetic device which can be used as an electronic article surveillance system marker. The method includes providing a substrate having a surface characterized by first and second generally perpendicular axes. A magnetic field oriented parallel to the first axis is applied on the surface of the substrate. A first stack of relatively thin thin-film magnetic layers separated by nonmagnetic thin-film layers is grown on the substrate. The relatively thin thin-tim layers are grown in the presence of the magnetic field to a thickness sufficiently thick that the layers exhibit magnetic properties that are substantially independent of surface effects, but sufficiently thin that the easy axis of magnetization is oriented parallel to the second axis. A second stack of relatively thick thin-film magnetic layers separated by nonmagnetic thin-film layers is grown on the first stack. The relatively thick thin-film layers are grown in the presence of the magnetic field to a thickness sufficiently thick that the easy axis of magnetization is oriented parallel to the first axis.
