THE USE OF TAPES FOR THE STORAGE OF DIGITAL DATA.
Abstract
Two of the more frequently used media for the storage of data in conjunction with digital systems are punched paper tape and magnetic tape. Both of these media are subject to errors. Paper tape, while cheaper to purchase than magnetic tape, exhibits a higher error rate per character. There are numerous error detection schemes used for both media including lateral and longitudinal parity, check characters based on the information content, knowledge of data patterns, and error detection codes. The correction of all errors is not possible. However, certain types of errors occur more frequently than others. Utilizing this fact it is possible to select an error correction scheme which will correct the greatest number or the most critical errors. Error correction schemes include deduction from parity, interpolation of related data, reconstruction from check characters, and a wide variety of specific error correction codes. (Author)
