摘要： A method of manufacturing a magnetic head includes the steps of: forming a pole-layer-encasing layer having a pole-layer-encasing section; and forming a pole layer in the pole-layer-encasing section. The pole layer includes a first layer, and a second layer formed thereon. The step of forming the pole layer includes the steps of: forming an initial first layer by physical vapor deposition; etching the surface of the initial first layer by dry etching so that the initial first layer becomes the first layer; and forming the second layer on the first layer.

摘要： A top surface of a pole layer of a magnetic head includes: a first portion having a first edge located in a medium facing surface and a second edge opposite thereto; and a second portion located farther from the medium facing surface than the first portion and connected to the first portion at the second edge. The distance from a substrate to an arbitrary point on the first portion increases with increasing distance from the medium facing surface to the arbitrary point. The angle of inclination of the first portion taken at the arbitrary point with respect to a direction perpendicular to the medium facing surface increases stepwise or continuously with increasing distance from the medium facing surface to the arbitrary point. The angle of inclination taken at the first edge is greater than zero degree. The second portion extends in a direction substantially perpendicular to the medium facing surface.

摘要： A magnetic head includes a pole layer, and an encasing layer having a groove that accommodates the pole layer. A manufacturing method for the magnetic head includes the steps of forming a nonmagnetic layer that will later undergo formation of the groove therein and will thereby become the encasing layer; forming the groove in the nonmagnetic layer so that the nonmagnetic layer becomes the encasing layer; and forming the pole layer such that the pole layer is accommodated in the groove of the encasing layer. The nonmagnetic layer is formed of Al2O3. The step of forming the groove in the nonmagnetic layer includes the step of taper-etching the nonmagnetic layer by reactive ion etching with an etching gas containing at least BCl3 and N2 among BCl3, Cl2 and N2.
