Abstract
An electrical lap guide (ELG) for use in lapping a bar of magnetic transducer carrying sliders to a desired height is disclosed. A first lapped or analog ELG element is positioned in a first dice lane on the bar between first and second sliders. A first electrical connection is positioned on a surface of the first dice lane for coupling the first ELG element to external circuitry. A second reference ELG element is positioned in the first slider at a position recessed from the lapped surface. A second electrical connection is positioned on the first slider for coupling the second ELG element to external circuitry.
