Abstract
The inadvertent introduction of stray fields at the media surface by the shields that form part of a magnetic read-write head has been eliminated by using a combination of masking and ion milling to remove small amounts of material close to the shields' outer edges. As a consequence, instead of presenting a sharp edge to the ABS, a shield's lower surface slopes gently away from it.
