PMR writer device with multi-level tapered write pole

A method of forming a multi-level tapered write pole for a PMR head, comprising:

• providing a substrate having a planar surface;
• forming in said substrate a trench, wherein a front portion of said trench is bounded by a front edge and a face extending therefrom into said substrate perpendicular to said substrate surface and said trench includes a downward sloped region extending rearward from said face and a flat region parallel to said substrate surface extending rearward thereafter;
• forming a bottom yoke in said trench, whereby said sloped region defines a 2nd taper on said bottom yoke and wherein a front edge of said bottom yoke is defined by said front edge of said trench;
• planarizing said bottom yoke;
• forming a main pole over said planarized bottom yoke, a front edge of said main pole extending forward beyond said front edge of said bottom yoke and defining an ABS of said main pole;
• forming a top yoke layer on said main pole, wherein said top yoke is vertically above and horizontally coextensive with said bottom yoke;
• forming on said top yoke layer a sloped region substantially mirror symmetric with respect to said sloped region in said bottom yoke;
• shaping said main pole to produce thereon a 1st taper;
• wherein
• said 1st taper ends a distance, d, before said front edge of said bottom yoke begins.
