    摘要: Methods for fabrication of tapered magnetic poles with a non-magnetic front bump layer. A magnetic pole may have a plurality of tapered surfaces at or near an air bearing surface (ABS), wherein a thickness of the write pole increases in a direction away from the ABS. A non-magnetic front bump layer may be formed on one or more of the tapered surfaces of the magnetic pole at a distance from the ABS. The front bump layer may increase the separation distance between a shield layer and the magnetic pole near the tapered surface, thereby improving the performance of the write head.

    摘要: A stepped main pole for a perpendicular write head and methods of making the stepped main pole. The stepped main pole has a main pole tip and a base portion. The main pole tip has a surface that forms part of the ABS and a first thickness. The base portion extends from the main pole tip and has a thickness that varies from the first thickness to a second thickness to form a slanted surface with an apex angle adjacent the main pole tip. By placing the base portion away from the ABS and providing a thickness that increases in a direction away from the ABS, the stepped pole can provide the necessary magnetic flux for writing, while avoiding undesired leakage and fringing. To form embodiments of the stepped main pole of the invention, a fluorine-based reactive ion etch (RIE) may be used. By using an RIE to define the stepped main pole, the apex angle can be better controlled and tight edge control can be achieved.

    摘要: Embodiments provide a slanted bump magnetic shield in a perpendicular write head and a method of making the shield. The slanted bump magnetic shield provides a small throat height to maximize magnetic flux for writing to a magnetic media such as a magnetic storage disk in a hard disk drive, while avoiding saturation. An etch process is used to form a taper in non-magnetic gap material. The magnetic shield is then deposited on the taper, forming the slanted bump of the shield. The etch process may be a multiple etch process to provide better edge and thickness control when forming the taper.
