ABSTRACT:
This relates to an apparatus for converting raw data into GCR data and for controlling the recording of GCR data on magnetic tape. An ordered series of instructions is stored in a first programmable read only memory (PROM). A second PROM contains a special character table and a code conversion table, and receives raw data. A third PROM stores addresses which are used to access the second PROM and are indicative of whether raw data is to be converted or a special character is to be generated.
