Abstract
To offer a Reed-Solomon decoding device that can effectively prevent erroneous correction. A Reed-Solomon decoding method that conducts error correction and decodes by using erasure positions showing the position of units of errors for a Reed-Solomon encoded string having parity data of 2t (positive integer) units, which finds the number n for the unit of the error from the above-mentioned erasure position (S,), in the event,≦m,≦n≦m,≦2t (m,, m,, and n are positive integers) (S,, S,, S,), finds the error value by conducting decoding calculations for the erasure error correction of n units (S,), and conducts the error operation by using the above-mentioned error value and the above-mentioned erasure position (S,).
