Longitudinal Redundancy Check
Block Redundancy Check
LRC

   <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 two errors in the
   individual characters of the string, beyond the odd errors.
