A magnetic head (slider) for perpendicular recording which requires no lapping is described. The head is fabricated with an air bearing surface that is parallel to the wafer surface. The coil and pole pieces are formed from thin films disposed parallel to the air bearing surface. Standard lithographic techniques can be used to define the shapes, gaps and pole piece dimensions. Non-rectilinear shapes can be formed; for example, side shields that conform around the write pole piece region. The thickness of the main and return pole pieces are controlled by the deposition process rather than by lapping. The saw cuts used to separate the individual sliders from the rest of the wafer are perpendicular to the air-bearing surface and do not pass through any critical features.
