Algebraic codes for improving the reliability of tape storage
Elwyn R. Berlekamp · 1975
This paper describes an operational software package for protecting the integrity of tape files with the use of a sophisticated algebraic code, which provides a large amount of protection against a wide variety of possible types of errors for a relatively modest amount of redundancy. The software is implemented on a Univac 1108 computer. Each 36-bit computer word is treated as three 12-bit digits.
