Abstract
A slider ( ) for reading data from a disk surface ( ), the slider ( ) including a magneto-resistive head ( ). The head ( ) includes a transducer ( ) having a stack of layers ( ), each layer ( ) having a proximal end ( ) proximal to the disk surface, and a pair of electrical leads ( ), connected to the transducer ( ), each one of the electrical leads ( ) also having a proximal end ( ) proximal to the disk surface ( ). At least one of the proximal ends ( ) of the electrical leads ( ) and the layers ( ) is recessed to provide one or more recessed areas ( ). The recessed areas ( ) are then filled with protective material ( ) to a depth such that when the layer of protective material ( ) is worn from the proximal ends ( ) by burnishing by the disk surface ( ), protective material ( ) still remains in the recessed areas ( ). Also disclosed is a method of fabrication of a slider ( ) having recessed areas ( ) filled with protective material ( ) which protect materials from corrosion and electrical spiking.
