Abstract
A thin film magnetic head assembly having a gap area upon which is deposited an electrically conductive by non-magnetically conductive material such as copper. This material, which may be placed directly adjacent to all faces of the gap except for the writing face thereof adjacent the recording media, acts to block the high frequency electromagnetic radiation from the sides and top of the gap by confining the electrical field within a very narrow layer of material. A layer of hard material may also be placed at or near the gap to protect the head core material from track-edge rolloff and pole tip recession.
