Patent ID: 6859997

Claim:
A method for manufacturing a magnetic write element for use in a data recording system, comprising the steps of: a. providing a first pole having a first and a second end and constructed of a magnetic material; b. depositing a dielectric write gap material layer over said first pole, said dielectric write gap material layer extending to said first end of said first pole and being formed so as to leave a portion said first pole uncovered at said second end of said first pole to provide a back-gap; c. depositing a mask material; d. patterning a coil pattern in said mask material using a photolithographic process; e. selectively removing a portion of said patterned mask material to produce a recess in said mask material in said pattern of said coil; f. forming a trench in said mask material adjacent said coil pattern, said trench having a depth that is shallower than a depth of said coil pattern recess; g. baking said mask material; h. depositing an electrically conductive coil into said coil pattern recess; i. removing said mask material; j. depositing a coil insulation layer; k. curing said coil insulation layer; and l. forming a second pole constructed of a magnetic material, said second pole contacting said first pole at said back-gap, and being separated from said first pole at said first end by said write gap material layer.
