Abstract

PURPOSE: To improve the angular detecting resolution by using a multi-polar magnetizing disc having a plurality of channels and a plurality of magnetic sensors which are arranged at a preset spacing.
CONSTITUTION: A multi-polar magnetizing disc 10, which is made rotatable together with a rotary member, has its circumference magnetized with N and S poles at a preset spacing l and is equipped in the thickness direction with a plurality of channels 10aW10e. One of these channels 10e is formed with a deficient portion K of the polarity for angular standard detection. In the channels 10aW10d, magnetic sensors 11aW11d are arranged to face. In the channel 10e, a magnetic sensor 11e is arranged to face. Here, the angular standard detecting sensors 11aW11d are arranged at a circumferential spacing of k/n×l from one another, wherein: k stands for an integer; and n stands for an angular channel number. By the use of the n channel disc and an n number of magnetic sensors, the resolution can be made n times that due to the magnetizing spacing of the magnetic disc.
