Abstract
Apparatus and method for correcting errors in data recovered from a magnetic medium includes detecting the data recovered from the read wave form, and performing an arithmetic operation such as division on the recovered data sequence to determine any non-zero remainder as an indication of an error event. The recovered data sequence is corrected in response to logical determination of a possible event error and position in the recovered data sequence from a collection of predetermined error and position for which the division of the corrected data sequence yields zero remainder.
