Patent ID: 7349180

Claim:
A magnetic write head having an air bearing surface (ABS) comprising: ferromagnetic first and second pole pieces in pole tip, yoke and backgap regions wherein the yoke region is located between the pole tip and back gap regions; a nonmagnetic electrically nonconductive write gap layer between the first and second pole pieces in the pole tip region; an insulation stack with at least one coil layer embedded therein between the first and second pole pieces in the yoke region; the first and second pole pieces being connected at said back gap region; first, second and third pole tip components which form a portion of the ABS with the pole tip portion of the first pole piece comprising the first pole tip component and the pole tip portion of the second pole piece comprising the second and third pole tip components; the second pole tip component being located between the first and third pole tip components and the write gap layer between the first and second pole tip components; the second pole tip component having a width at the ABS that defines a track width of the write head; the third pole tip component having top and bottom surfaces with a first bottom surface portion of the bottom surface interfacing the second pole tip component and having a width that is equal to the width of the second pole tip component; the top surface of the third pole tip component having a width that is greater than the width of the first bottom surface portion; said bottom surface having second and third bottom surface portions which are parallel to said first bottom surface portion; the bottom surface having a fourth bottom surface portion which extends between the first bottom surface portion and the second bottom surface portion with a surface of the fourth bottom surface portion forming an obtuse angle with respect to a surface of the second bottom surface portion and the bottom surface having a fifth bottom surface portion which extends between the first bottom surface portion and the third bottom surface portion with a surface of the fifth bottom surface portion forming an obtuse angle with respect to the surface of the third bottom surface portion, and the bottom surface of the third pole tip component having sixth and seventh bottom surface portions with the second bottom surface portion located between the fourth bottom surface portion and the sixth bottom surface portion, with the third bottom surface portion located between the fifth bottom surface portion and the seventh bottom surface portion and with a surface of the sixth bottom surface portion forming an angle greater than 180° with respect to a surface of the second bottom surface portion and a surface of the seventh bottom surface portion forming an angle greater than 180° with respect to a surface of the third bottom surface portion.
