ABSTRACT:
A wear-resistant end cap is provided for an air bearing slider of a thin film magnetic recording head useful in a disk drive. The slider has an air bearing surface that is positioned adjacent to a rotating surface of a magnetic disk during data recording or readout. A thin film transducer is deposited on the trailing end of the slider perpendicular to the air bearing surface. A laminated end cap is deposited on the trailing end surface disposed normal to the disk recording surface to protect the transducer. The end cap includes a first lamination disposed with an edge in a plane parallel to the air bearing surface of the slider and a second contiguous lamination of a different material having an edge in the plane whereby the edge areas of the contiguous laminations have relatively more wear resistance than the wear resistance of an equivalent edge area of either material taken alone.
