Abstract

PURPOSE: To improve the reliability of the correction by an eraser, by carrying out eraser correction by regarding a pointer as correct when a specific condition is established from a wrong-position polynominal formed of a value corresponding to wrong position indicated by the pointer.
CONSTITUTION: When a condition deg σ*(x)>deg ω*(x) is established when a wrong position polynominal formed of a value corresponding to the wrong position indicated by a pointer is expressed as σ*(x) and the σ*(x)S(x) found by multiplying the wrong position polynominal σ*(x) by a syndrome polynominal S(x) is expressed as a polynominal ω*(x), eraser correction is carried out by regarding the pointer as correct. Therefore, whether or not the pointer indicates all wrong positions can be checked and highly reliable eraser correction can be carried out.
