Abstract

The specification discloses a first and a second rotary disk fixed together, each disk having a magnetic pole on its circumference, which disks rotate in the vicinity of a fixed magnetic head; the fixed magnetic head provides an electrical output signal each time a magnetic pole passes near it and, thus, said electrical output signal indicates a rotational angle and/or the number of rotations of said disk. Said magnetic head operates on a new principle developed from parametric excitation.
