1. A linear measuring system, comprising:
- a scale including at least two segments identically created for the generation of absolute values, each of said at least two segments including a measurement track for generating the absolute value within said segments recorded by an appropriate scanning head, and at least one suitable track for determining the absolute value of the particular segment reached by a sensor arrangement; and
a switching device using the generated absolute value within said segments and the determined absolute value of said segment to provide the total absolute value for further processing;
said scale being a structured material characteristic or a structured surface on a material.

Abstract
A measuring system for the recording of angular or position values, wherein the scale includes a measurement track with absolute encoding, and which is scanned by a sensor is provided.
The scale is composed of at least two segments with similar absolute encoding, and a suitable track is provided on the scale with which the absolute value of the particular segment reached is calculated by a further sensor arrangement. The total absolute value is then gained from the combination of both absolute values.
