A real-time transputer-based system for a digital recording data channel

Abstract A number of techniques found useful when using a Transputer, programmed in occam, as the data processing element in the data channel of a four-track compact-cassette digital magnetic tape recorder are described. A simple circuit has been designed which multiplexes the asynchronous data from the four tracks down a single Link. The Transputer's ability to handle parallel processes, and to accurately time events has been utilised to solve the problems caused by tape skew.
