PROBLEM TO BE SOLVED: To detect the eccentric state of a detecting gear using a disc without tooth and furthermore to use an eccentricity detection output indicating the eccentric state to correct the amplitude of an encoder signal. SOLUTION: This magnetic encoder and its output method use a disc (3) that has the same core as a detecting gear (2) and no tooth, and an eccentricity detection output (6) that the eccentric state of the disc (3) is detected is used to correct the amplitude of an encoder signal (4), resulting in a corrected encoder signal (5A) that is accurate and is not affected by eccentricity.
