Abstract

PURPOSE: Not only to remove interference of a mutual reading-out voltage amplitude, but also to prevent drop of resolution due to densification of a magnetic record, and to eliminate occurrence of a peak shift efficiently, by applying an electric current only during a proper time to a section of a positive logic of a signal series that is a part of an elemental input data signal series.
