摘要： A manufacturing method for a perpendicular magnetic recording head includes the steps of forming a groove in a first nonmagnetic layer, forming a side shield, forming a second nonmagnetic layer, forming a main-magnetic-pole front end portion and forming a main-magnetic-pole yoke portion. The groove extends in a front-rear direction orthogonal to an air bearing surface. The side shield of soft magnetic material, the second nonmagnetic layer and the main-magnetic-pole front end portion of soft magnetic material are formed on an inner wall of the groove. The main-magnetic-pole front end portion is not magnetostatically coupled to the side shield. The main-magnetic-pole yoke portion magnetically is insulated from the side shield and magnetically connected to the main-magnetic-pole front end portion. The main-magnetic-pole yoke portion widens from the main-magnetic-pole front end portion toward a rear side.

摘要： A perpendicular magnetic head suppresses pole erasing due to a remanent magnetization component of a main pole and is capable of higher density recording. The perpendicular magnetic head is equipped with a main pole that produces magnetic flux toward a medium surface of a recording medium as a write head. The main pole is formed by laminating two thin magnetic layers in the thickness direction. Out of the thin magnetic films, a top thin magnetic film is formed as a high Bs thin magnetic film with a first saturation flux density and a bottom thin magnetic film is formed as a low Bs thin magnetic film with a second saturation flux density that is lower than the first saturation flux density, and the high Bs thin magnetic film and the low Bs thin magnetic film satisfy the following equation (volume of the high Bs thin magnetic film)×(first saturation flux density)

摘要： The method of forming a plated pattern is capable of securely narrowing and miniaturizing a resist pattern, which has been hydrophilic-treated, without widening and deforming the resist pattern. The method comprises the steps of: covering a surface of a plating seed layer with resist; exposing and developing the resist so as to form a resist pattern having a concave part; executing a hydrophilic treatment of the resist pattern; piling a metal in the concave part of the resist pattern by plating; removing the resist pattern; and removing an exposed part of the plating seed layer. The plating seed layer is a volatile metal layer made of a metal, which is oxidized during the hydrophilic treatment, and an oxide of the metal constituting the volatile metal layer has volatility.
