ABSTRACT:
In constructoin of a magnetic recording medium provided with one circular track for magnetic graduations and another circular track for standard marks, the standard marks are accompanied with specified magnetic identification marks so that discrimination between the standard marks can be fairly done without any influence by the number of the standard marks only by reading them out together with the identification marks. The medium is advantageously used for displacement detectors such as magnetic rotary encoders and magnetic linear scales.
