METHOD FOR MANUFACTURING A PERPENDICULAR MAGNETIC WRITE HEAD HAVING A TAPERED WRITE POLE |
摘要 |
A method for manufacturing a magnetic write head having a write pole with a tapered leading edge and a tapered trailing edge. The method includes forming a non-magnetic bump player over a surface, forming a mask over the non-magnetic bump layer and performing a first ion milling to form a tapered back edge on the non-magnetic bump layer. A magnetic write pole material is then deposited over the surface and over the non-magnetic bump layer. Then a non-magnetic step structure is formed over the magnetic write pole material and an ion milling is performed to form a taper on the upper surface of the write pole. The write pole lateral dimensions can then be defined, and a non-magnetic bump formed over the tapered portion of the upper surface of the write pole. Another ion milling can then be performed to extend the taper of the surface of the write pole.
