Abstract: A magnetic head having non-GMR shunt for perpendicular recording and method for making magnetic head having non-GMR shunt for perpendicular recording is disclosed. A shunt is provided for shunting charge from a read sensor. The shunt is formed co-planar with the read sensor and is fabricated using non-GMR materials.

Abstract: A method of making a magnetoresistive sensor includes defining a track width of a magnetoresistive element stack of the sensor with a hard mask and photoresist. Further, processes of the method enable depositing of hard magnetic bias material on each side of the stack after the hard mask used to define the track width is removed. A separate chemical mechanical polishing (CMP) stop layer that is different from the hard mask enables subsequent creating of a planar surface via CMP to remove unwanted material on top of the sensor stack.

Abstract: One embodiment in accordance with the invention is a method comprising depositing a material above a disk substrate. The disk substrate is for a data storage device. The material above the disk substrate can be nanoimprinted. The material can be processed to transform it into a substantially solidified material. A magnetic material can be deposited on the substantially solidified material.

Abstract: The present invention provides a novel high magnetic moment material for the pole pieces as well as a metal-in-gap configuration for the pole tips of either an inductive magnetic head only or the inductive portion of a MR head. The novel material is Ni.sub.45 Fe.sub.55. In the MIG configuration each pole piece of the inductive head or the inductive head portion of a MR head has a combination of layers, each combination of layers including a first layer of high magnetic moment material Ni.sub.45 Fe.sub.55 adjacent to a transducing gap and a second layer of low magnetic moment material such as Permalloy (Ni.sub.81 Fe.sub.19) further away from the gap. Since both layers are made of NiFe all the desirable properties of this type of material can be employed as well as simplifying its construction with similar plating baths. The saturation of the first layers is 50 to 60 percent higher than the saturation of the second layers.

Abstract: In a magnetic read/write transducer, the elements of the magnetoresistive (MR) and inductive heads are shorted together and to the slider substrate to provide a low resistance, conductive path bypassing the MR sensor element and minimizing electrical current through the MR sensor element during discharge of static electric charge. The MR sensor element, the MR conductive leads, the MR magnetic shield elements and inductive pole tips exposed at the slider air bearing surface are shorted together and to the slider substrate by a layer of conductive material, such as tungsten, formed over the slider air bearing surface. The conductive layer shorts the head elements together and to the slider substrate thus protecting the head against ESD/EOS damage during subsequent handling and assembly. The conductive layer is removed by wet etching prior to placing the magnetic head into operation in a magnetic storage system.

Abstract: A horizontal thin film magnetic head is provided which has well aligned pole tips. The head includes first and second seedlayers, the first and second seedlayers being located below a first pole tip and only the second seedlayer being located below the second pole tip. The first pole tip may be capped with a nonmagnetic material such as copper. A very narrow sidegap is employed between the first and second pole tips.

Abstract: The magnetoresistive (MR) sensor in a magnetic read/write transducer is protected against the effects of electrical overstress and electrostatic discharge during the manufacture and assembly of a magnetic storage system. The conductive leads of a magnetoresistive (MR) sensor element are shorted together to provide a low resistance, conductive path bypassing the MR element and minimizing electrical current through the MR sensing element during discharge of static electrical charge. The MR sensor lead terminal pads provided on the transducer/slider surface are shorted together by soldering. The other transducer elements such as the MR magnetic shields, the inductive coil and the inductive magnetic yoke structure can also be shorted to the MR sensor leads by soldering together the lead terminal pads at the slider surface. Alternatively, a twisted conductor pair may be used to short the MR terminals together.

Abstract: A simplified method is provided for making a thin film magnetic head pole tip structure which includes a sidegap G sandwiched between pole tips PT1 and PT2. The method includes depositing bottom and top seedlayers with an insulation layer sandwiched therebetween. The pole tip PT2 is frame plated on top of the top seedlayer with top and bottom film surfaces which are bounded in part by a pair of spaced-apart sidewalls. The second seedlayer and preferably a depth portion of the insulation layer are removed with the exception of width portions of these layers below the pole tip PT1. A gap insulation layer is deposited on a sidewall of the pole tip PT1 to form the sidegap. The insulation layer with the exception of a portion of an insulation layer below the pole tip PT1 is removed to expose a portion of the bottom seedlayer adjacent to the pole tip PT1 where the pole tip PT2 is to be formed.
