Abstract
An absolute position encoder for identifying which of a plurality of loci a moveable member occupies comprises a plurality of data tracks in which binary data is encoded to form a series of n-bit words, each of the plurality of loci being associated with one of the n-bit words. A plurality of the n-bit words is required to uniquely determine which of the loci the moveable member occupies. The absolute position encoder does not use a clock track to resolve the problem of asynchronous bit transitions.
