A method of manufacturing a magnetic write head for perpendicular magnetic
recording. The method includes the formation of a write pole over a
substrate. A non-magnetic side gap layer is deposited and an ion milling
is used to remove a portion of the substrate to lower the floor of the
substrate. A sacrificial fill layer can then be deposited. A chemical
mechanical polishing process can be used to remove the mask structure
remaining as a remnant of the formation of the write pole, and then the
sacrificial fill layer can be removed. A non-magnetic, electrically
conductive material can be deposited to form a tailing gap, an a magnetic
material can then be deposited to form a wrap around trailing shield.
