摘要： A method for manufacturing a magnetic write head having a non-magnetic step layer, non-magnetic bump at the front of the non-magnetic step layer and a write pole with a tapered trailing edge. The tapered portion of the trailing edge of the write pole is formed by a two step process that allows the write pole taper to be formed with greater accuracy and repeatability than would be possible using a single step taper process. An alternative method is also described on how to make a non-magnetic bump structure with adjustable bump throat height prior to Damascene side shield gap formation in a Damascene wrap around shield head.
