METHOD AND STRUCTURE FOR DEFINING TRACK WIDTH ON A RECORDING HEAD

METHOD AND STRUCTURE FOR DEFINING TRACK WIDTH ON A RECORDING HEAD

A head structure for writing data on a magnetic media including a first pole having an upper surface and a write gap covering a portion of the upper surface. An upper pole tip formed on the write gap having a first width. A second pole having a second width greater than the first width and coupling...

Zusammenfassung:A head structure for writing data on a magnetic media including a first pole having an upper surface and a write gap covering a portion of the upper surface. An upper pole tip formed on the write gap having a first width. A second pole having a second width greater than the first width and coupling to an upper surface of the upper pole tip. A conductive coil magnetically coupled to the first pole and the second pole to induce magnetic flux within the first and second pole in response to a current flowing in the coil.
