A method and system for providing a writer is disclosed. The method and system include providing a first pole, an insulator covering a portion of the first pole and a coil on the first insulator. The coil includes a plurality of turns. The method and system also include providing a second insulator covering the coil, providing a second pole on the second insulator and providing a write gap separating a portion of the first pole from a second portion of the second pole. A first portion of the second pole is coupled with the first pole. In one aspect, the method and system include providing a coil having a plurality of turns with a pitch of no more than 1.2 micrometers. In another aspect, the plurality of turns of the coil is provided using a hard mask layer on a photoresist layer. A portion of the hard mask layer and a portion of the photoresist layer define a plurality of spaces between the pluralities of turns of the coil. In another aspect, the writer is a pedestal defined zero throat writer. In this aspect, the first insulator has a depression therein and the coil is provided on the depression.
