1. A method of encoding a block of data comprising in combination the steps of:

  • generating a plurality of check symbols from said data with an interleaved Reed-Solomon code with a generator polynomial
    
    
    space="preserve" listing-type="equation">g(x)=g.sub.0 (x.sup.h), where x is a variable, h is the degree of interleaving, and g0 (x) is a generator polynomial of the form ##EQU3## where
    
    
    space="preserve" listing-type="equation">v=2.sup.m-1 -2,α

    is a primitive element of the Galois field GF(2m), a is a positive integer, b is a positive integer, and m is a positive integer; and

    appending said check symbols to said data.
