发明名称 Magnetic head for perpendicular magnetic recording system and process.
摘要 <p>A disc drive is disclosed incorporating a non-magnetic slider supporting a read/write head (10) for use in reading and recording data on perpendicular magnetic recording media (12), the head comprising a first elongate member (26) of magnetic material having a thin film pole piece (20) extending longitudinally along the face thereof, the pole piece terminating at the end (22) of the elongate member and proximate the recording media in a pole tip end (24) that has a width and thickness operable to establish the resolution of the head when the head is used for recording or accessing the information. The head further comprises a U-shaped member having a base member (32) and two legs (34,36), one (34) of the legs being fastened to the upper end of the elongate magnetic member. The second leg (36) is positioned a short distance from the pole tip end (24) of the thin film magnetic pole, the leg of the U-shaped member functioning as a flux collector and its spacing from the pole tip end defining the recording gap. The U-shaped member (64-Fig.3) is initially formed with a portion of the lower leg (70) incorporating a step (74) and an elongate bar (54) deposited with thin film (56) to function as the pole tip end (24) is bonded to the member (64). By lapping off the bottom portion of the elongate member, the thin film pole piece which it carries, and the lower leg of the U including the entire step portion, a pole tip having a flat bottom surface and supported by an elongate magnetic member and spaced a fixed distance from the flux collecting tip of the U- shaped member of the head is formed.</p>
