A METHOD OF INCREMENTAL RECORDING ON MAGNETIC TAPE
Abstract
The conventional method of recording pulse data on magnetic tape fails to fully utilize the optimum bit-packing capability of the recording tape at pulse rates less than the design maximum. A simple method of incremental recording is described wherein the tape is stepped one increment of length for each serial input pulse, allowing optimum bit packing which is independent of pulse rate. The method is applicable to multi-channel recording of variable pulse rates up to 100 pps and TO recording mediums other than magnetic tape. It is advantageous where low power drain and long recording time without tape reloading are required. An experimental miniature incremental magnetic tape recorder, utilizing a commercially available stepping motor and having transistorized logic and drive circuitry is described. Test results are given and a method of data analysis for incrementally recorded tape by means of conventional playback is presented.
