Disclosed are absolute measuring systems comprising measuring rods that are composed of groups of at least two magnetic segments. The magnetic segments of at least one group have the same length in the direction of measurement while the magnetic segments of the different groups have different lengths. For arrangements encompassing more than two sensors on the single-track measuring rods, multistage phase difference processes are disclosed which result in high resolutions and accurate measurements while allowing for great measured lengths and, when anisotropic magnetoresistive sensors are used, for example, an unambiguous angle measurement range of 360°. FIG. 6a best represents the essence of the invention.

An arrangement for absolute determination of a linear position or of a rotation position expressed by an angle of two bodies adapted to be displaced or rotated relative to one another, comprising:
A method for absolute determination of a linear position or of a rotation position expressed by an angle of two bodies that can be displaced or rotated relative to one another, with a first body having a scale with a plurality of magnetic segments that alternate in polarity in a measurement direction, a second body having at least two spaced-apart magnetic-field-sensitive sensors, and an evaluation unit, wherein the scale is composed of groups having each at least two magnetic segments, with a length of the at least two magnetic segments in the measurement direction in at least one group being identical to one another, and lengths of the magnetic segments of different groups being different from one another, the method comprising the steps of:
