New Shielded Single-Pole Head With Planar Structure

A planar-type single-pole head for perpendicular magnetic recording which is combined with multicharged-surface main-pole structure for a strong head field and with a wraparound shield for steep head field distribution has been newly devised. The head field strength of the new head is less influenced by the thickness of the shield compared with that of the conventional shielded single-pole head whose pole tip is straight. This new head was fabricated using a different technique from the present head
