ABSTRACT:
An encoder system for providing a large number of actual positional control pulses per revolution utilizes an optical digital disc. The disc is driven by the work piece transport system. A playback unit similar in construction to audio disc players can be used. The positional control information is recorded on the disc as the disc is being driven by the transport system with which the disc is to be associated. Mechanical anomalies of the drive system are compensated for in the recording process. The accuracy of the positional information is improved. The system is especially useful for high resolution ink jet printing system.
