摘要
A method for manufacturing a code disk for devices such as optical incremental shaft encoders and absolute shaft encoders employs the step of first assembling a code disk which is to be inscribed with a selected code pattern on a mounted shaft, prior to the inscription of the code pattern. The code pattern is subsequently inscribed on the surface of the code disk with a laser beam transmitter as the disk rotates about the shaft. The code disk is precisely positioned in relation to the laser beam transmitter by an angular step control device and the code pattern on the code disk is also precisely positioned with respect to the mounting location in the central area of the code disk.
