Patent ID: 6857181

Claim:
A method of making a magnetic write head comprising the steps of: forming ferromagnetic first and second pole pieces in pole tip, yoke and back gap regions wherein the yoke region is located between the pole tip and back gap regions; forming a nonmagnetic electrically nonconductive write gap layer between the first and second pole pieces in the pole tip region; forming an insulation stack with at least one coil layer embedded therein between the first and second pole pieces in the yoke region; connecting the first and pole pieces at said back gap region; forming 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; forming the second pole tip component between the first and third pole tip components and the write gap layer between the first and second pole tip components; further forming the second pole tip component with a width at the ABS that defines a track width of the write head; further forming the third pole tip component with 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; further forming the top surface of the third pole tip component with a width that is greater than the width of the first bottom surface portion; forming said bottom surface with second and third bottom surface portions which are parallel to said first bottom surface portion; forming the bottom surface with 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 first bottom surface portion and the bottom surface with 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 first bottom surface portion; and forming the bottom surface of the third pole tip component with 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 with a surface of the sixth bottom surface portion forming an obtuse angle with respect to a surface of the second bottom surface portion and a surface of the seventh bottom surface portion forming an obtuse angle with respect to a surface of the third bottom surface portion.
