Method of manufacturing a magnetic recording transducer

A method for manufacturing a magnetic recording transducer comprising:

• providing a first pole having a front portion and a rear portion;
• providing a back gap on the rear portion of the first pole;
• providing an insulator on the first pole, a first portion of the insulator being adjacent to the back gap;
• providing a write gap, a portion of the write gap residing on the front portion of the first pole;
• providing a portion of a second pole on at least the write gap, a second portion of the insulator covering a remaining portion of the first pole between the portion of the second pole and the back gap;
• providing a mask covering the back gap and exposing the portion of the second pole and the insulator;
• and
• performing a pole trim for the portion of the second pole, wherein the pole trim perform further includes:
• allowing the pole trim to substantially remove the portion of the insulator covering the remaining portion of the first pole between the portion of the second pole and the back gap.
