Abstract: A method for manufacturing a magnetoresistive sensor that results in the sensor having a very flat top magnetic shield. The process involves depositing a plurality of sensor layers and then depositing a thin high density carbon CMP stop layer over the sensor layers and forming a mask over the CMP stop layer. An ion milling is performed to define the sensor. Then a thin insulating layer and magnetic hard bias layer are deposited. A chemical mechanical polishing is performed to remove the mask and a reactive ion etching is performed to remove the remaining carbon CMP stop layer. Because the CMP stop layer is very dense and hard, it can be made very thin. This means that when it is removed by reactive ion etching, there is very little notching over the sensor, thereby allowing the upper shield to be very thin.

Abstract: Embodiments of the present invention help to provide a flying height adjusting type magnetic head slider with reduced influence of a heater coil induction field. According to one embodiment, a magnetic head slider comprises a heater, a read element, and a write element, which are formed on a substrate. The heater is formed between a lower magnetic shield of the read element and the substrate by meandering a heater coil in direction Y going away from ABS. Magnetic fields by generated in direction Y orthogonal to a track width direction X of the lower magnetic field upon energization of the heater coil are offset each other, exerting no influence on the magnetized state in the track width direction X of the lower magnetic shield. A magnetic field hx induced in the track width direction X of the lower magnetic shield is coincident with the magnetizing direction of the lower magnetic shield, acting to maintain the magnetized state of the lower magnetic shield.
