Abstract
This application discloses a method for generating and detecting address marks in data fields which are not provided with readily useful clock pulse means. The method comprises inverting portions of a digital word during writing of an address mark and reinverting words during reading of a record, whereby only inverted, i.e. address mark portions, of said word provide an indication of error-free reading during a read operation provided with error detection means.
