Abstract:

This paper tabulates the results of initial tests conducted to determine the data reliability of three methods of recording Bell A1 digital data on magnetic tape. The tests were designed only to find an approximate figure for error rate in that the following parameters were held constant 1 type tape, 2 tape age, 3 position of information across tape channel effects, 4 position of information along tape reel effects, and 5 word length. More tests are necessary to determine the effect of these parameters on error rate. The results show that the three recording systems tested are adequate for their application.
