摘要： A slider includes a magnetic head having first and second magnetic poles separated by a gap. A recess in the air-bearing surface extends into at least the first magnetic pole and has a first portion having a length parallel to the gap length to define a gap width orthogonal to the gap length. The first portion of the recess has a curved depth defining a curved profile along its length. In one embodiment, the recess has a second portion having a length orthogonal to the gap length and a depth defining a curved profile along its length.

摘要： A magnetoresistive element has a height that extends from the air-bearing surface of a head. The height is determined by a slot in the head extending from the air-bearing surface adjacent the sensor portion at an acute angle to both the air bearing surface and the height of the magnetoresistive element to separate the magnetoresistive element into the sensor portion and a dormant portion. Alternatively, the height is determined by a recess of design depth in the magnetoresistive element at the air bearing surface. Alternatively, the height of the magnetoresistive element is determined by a stepped thickness to the first and second bias current carrying contacts along the height of the magnetoresistive element.

摘要： A disc storage system includes a rotating disc and a transducer. The transducer is carried on a slider which is supported by an armature. The armature is used to move the slider radially across the disc surface whereby information may be read from or written to the disc surface of the transducer. The slider includes an air bearing surface which faces the disc surface. As the disc rotates, the air bearing surface causes the slider to “fly” over the disc surface. Pads are provided on the air bearing surface to improve operational characteristics of the system.

摘要： A method for producing magnetoresistive heads includes the steps of placing a substrate having a plurality of transducers in an environment including a focused ion beam. The focused ion beam is directed onto the first MR element. A property level, generally the resistance associated with the MR stripe, of the first MR element is monitored until the resistance reaches a desired level. The focused ion beam is redirected onto a second area of the substrate which includes the second MR element. The electrical resistance of the second MR element is monitored as the focused ion beam acts on the second MR element until the resistance of the MR element reaches a desired level. Using this process, the resistivity of individual MR elements within the substrate can be tightly controlled.

摘要： The present invention is a method of using direct head electrical response signals for feedback process control. When lapping the air bearing surface of a bar of sliders, a magnetic field is applied to the air bearing surface and a bias current is applied to the reader elements. A head electrical response, such as amplitude or resistance change, is measured and is used to control the lapping device. Using a fixture which allows individual slider machining, a controller can be used to monitor the head response signal for each slider on the bar and individually control each slider on the bar so that material removal over each slider proceeds until a predetermined target stripe height is reached.
