1. A type of Reed-Solomon coding device that can handle multiple RS (Reed-Solomon) codes using different field generation polynomials, comprising:

  • means for storing multiple multiplication coefficient sets corresponding to multiple code-forming polynomials;

    switching means for selecting one of said coefficient sets;

    a Galois field transformation means that transforms the input data to the data of a prescribed Galois field;

    a coding means that performs coding processing using a selected multiplication coefficient set for the aforementioned transformed data by means of the aforementioned Galois field after transformation; and

    a Galois field inverse transformation means that undertakes inverse transformation of the coded data of the aforementioned Galois field to a Galois field before transformation.
