Longitudinal Redundancy Check

storage, communications (LRC, Block Redundancy Check) An

error checking method that generates a longitudinal parity

byte from a specified string or block of bytes on a

longitudinal track.

The longitudinal parity byte is created by placing individual

bytes of a string in a two-dimensional array and performing

a Vertical Redundancy Check vertically and horizontally on

the array, creating an extra byte. This is an improvement

over the VRC because it will catch an odd number of errors in

the individual characters of the string.
