A1
Abstract:
The present disclosure discloses a code disc and an encoder, the code disc comprises: a code track assembly coded in a set coding manner, and a fixed grating corresponding to the code track assembly, wherein the coding manner is used to improve the width of an absolute window of the code track assembly. The solution of the present disclosure can solve the problem of reducing the reliability of the encoder as the absolute signal window is narrowed caused by the increase of the number of the scribed lines of the increment code track, achieving the effect of improving the reliability of the encoder.
