Abstract
Magnetic poles are regularly spaced along a path to form a magnetic track. Some of the magnetic poles are separated by regular pole junctions aligned uniformly with respect to the path of the magnetic track. At least two of the magnetic poles are separated by a skewed irregular pole junction aligned such that a sensor near an edge of the magnetic track will sense a wide pole and a narrow pole to allow an index signal to be produced.
