A Double Track Error-Correction Code for Magnetic Tape
Prusinkiewicz, Budkowski · IEEE Transactions on Computers · 1976
An error-correction code, presented here, uses two redundant tracks and one redundant character which are formed from the askew and the vertical redundancy check (AVRC) bits. The error-correction capability of this code is the same as for the ORC Patel and Hong's code, but the encoded codeblock dimension is not subject to constraints.
