ABSTRACT:
A method for detecting and correcting an error that has occurred in a digital computer, comprises the steps of: counting the number of mark bits in each predetermined area of each of component units constituting data, each of the component units being expected to be represented by one of reference representations; detecting the occurrence of an error in the area when the count value is not identical with any of preset reference values in the corresponding areas; and correcting the component unit of the data in which the error has been detected, by a reference representation having a reference value in the corresponding area which is the closest to the count value.
