New shielded single-pole head with planar structure

Abstract

A planar type single-pole head for perpendicular magnetic recording which is combined with multi-charged-surface (MCS) main-pole structure to produce a strong head field and with a wrap-around shield to 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.
