Perpendicular recording write head having a recessed magnetic adjunct pole and method of making the same

A data storage system including a thin film write head for perpendicular magnetic recording, the write head comprising:

• a first pole (P1) made of a magnetically conductive material, that provides a return path for a magnetic flux during a write operation onto a medium;
• an inductive write coil disposed atop the first pole (P1);
• an adjunct pole mode of a thin film magnetically conductive material and disposed atop the write coil;
• the adjunct pole includes a forward edge that is recessed from an air bearing surface (ABS) level;
• and
• a main pole for writing data onto the medium, that is formed over the adjunct pole and that extends to the ABS level.

A method of making a thin film write head for perpendicular magnetic recording, comprising the steps of:

• forming a first pole (P1) of a magnetically conductive material, to provide a return path for a magnetic flux during a write operation onto a medium;
• forming an inductive write coil atop the first pole (P1);
• forming an adjunct pole of a thin film magnetically conductive material, atop the write coil;
• recessing the adjunct pole from an air bearing surface (ABS) level;
• and
• forming a main pole for writing data onto the medium, over the adjunct pole wherein the main pole extends to the ABS level.
