Patent ID: 7386933

Claim:
A method of fabricating a thin film write head, comprising: forming a first magnetic pole with an upper surface; removing a portion of the upper surface to create a bottom of a coil trench; depositing a layer of write gap material on the upper surface of the first magnetic pole and at least a portion of the bottom of the coil trench; forming a first layer of a second magnetic pole, wherein the first layer includes a front pole tip and a back pole tip each having interior side walls substantially perpendicular to the upper surface of the magnetic pole and being space apart so as to define sides of the coil trench; depositing a film of insulating material over the side walls of the pole tips and the bottom of the coil trench; and forming an electrically conducting coil with coil insulation materials upon the deposited film of insulating material, the coil insulation materials filling the coil trench.
