Abstract

PURPOSE: To obtain accurate angle signal from individual element, by changing the width of a plurality of strip shape magnetic resistance effect elements which detect the change in magnetization of the magnetic memory medium formed on the circle, accordance with the distance to the magnetic memory medium.
CONSTITUTION: The rotating shaft 10 is fitted with the disc 13 having the magnetic memory medium 12 in which magnetic signal is recorded in the form of magnetization 11 having the bit length P of equal interval along the circle. The magnetic sensor 8 is provided for the disc 13 to enable to detect the magnetic signal magnetic field 14. Since the magnetic resistance effect element 1 at the end of the magnetic sensor 8 is remote in the distance from the magnetic memory medium in comparison with the elements 2, 3 near the center of the magnetic sensor 8, the width is made greater to increase the sensitivity of reproduction.
