A magnetic sensor including a first layer that is a pinned layer, the first layer having a first edge. The magnetic sensor includes a second layer that is a non-magnetic metal layer, the second layer having a second edge corresponding to the first edge. The second layer is adjacent the first layer. The magnetic sensor includes a third layer that is a free layer, the third layer having a third edge corresponding to the first edge and the second edge. The third layer is adjacent the second layer. The magnetic sensor also includes a fourth layer that is a flux guide layer. The fourth layer is adjacent the third layer. The fourth layer extends outwardly from the third layer relative to the first layer and the second layer.

A corrosion-resistant magnetic sensor and a method for making the corrosion-resistant magnetic sensor. The magnetic sensor includes a first layer that is a pinned layer, the first layer having a first edge. The magnetic sensor also includes a second layer that can be a non-magnetic metal layer, the second layer having a second edge corresponding to the first edge, wherein the second layer is adjacent the first layer. The magnetic sensor also has a third layer that can be a free layer, the third layer having a third edge which projects outwardly relative to the first edge and the second edge.

A multilayered ferromagnetic laminate includes a first magnetic film having a cobalt alloy and a second magnetic film having an iron-nitrogen alloy. The films are deposited upon one another and laminated to provide a multilayered film structure having an alternating plurality of the first and second magnetic films. The cobalt alloy may be a cobalt-zirconium-tantalum alloy. The nitrogen is incorporated interstitially in the crystalline structure of the iron of the second magnetic film. The laminate forms the magnetic shields and the write poles of magnetic disk and tape heads. The lamination of the first magnetic film which has high electrically resistive, high mechanical hardness, and high magnetic moment characteristics with the second magnetic film which has lower electrically resistive and very high magnetic moment characteristics yields the laminate which has very high magnetic moment and very hard pole material characteristics and has the ability to write at high frequencies.

A system for reducing signal crosstalk in a flexible trace interconnect array includes a flexible dielectric material base, and a plurality of conductors longitudinally arranged as pairs in a signal layer array on the base. At least one of the pairs of conductors comprises a twisted pair.
