Abstract
Some embodiments of the invention relate to an absolute code scale of an angle or linear position encoder, which is composed of a first absolute code sequence having a first primary code period length, which is periodically continued, and at least one second absolute code sequence having a second primary code period length, which is periodically continued. The first and the at least one second absolute code sequence are codeword-foreign in relation to one another in this case. Along the absolute code scale, in each case one section from the first and one section from the at least one second absolute code sequence are successively arranged alternately and in this case the absolute code sequences are each shifted in relation to one another in the different sections from the same absolute code sequence along this arrangement.
