Abstract:
The present disclosure provides a magnetic medium, a magnetic encoder, and a method for manufacturing a magnetic medium with high reliability that can obtain the sufficient signal output, while reducing the hysteresis error. The magnetic medium is relatively movable with respect to a magnetic sensor for detecting a magnetic field in a magnetosensitive face.
