Abstract:
A method for fabricating sliders containing magnetic transducer elements comprising the steps of:forming one or more magnetic transducer elements on a wafer surface of slider body material; forming a mask on the wafer surface to define a location, dimensions and shape of a slider that includes at least one magnetic transducer element, the shape of the slider having a sacrificial extension which extends through a predetermined plane at which lapping will be terminated, the sacrificial extension being narrower than a width of the slider; cutting the slider out of the wafer by etching away material outside of the mask, the etching forming the sacrificial extension of a surface of the slider which extends generally perpendicular to the surface of the wafer; and lapping the slider surface including the sacrificial extension until the predetermined plane has been reached.
