  • Method of fabricating magnetic recording heads using asymmetric focused-Ion-beam trimming
    Publication number: 20030127424
    Abstract: A method of fabricating a magnetic structure, the method including: forming a first magnetic structure having a first side and a second side, and using a focused ion beam to etch only one of the first and second sides, to reduce a width of the magnetic structure. The first magnetic structure can be formed using a full-field lithographic technique such as optical lithography. The magnetic structure can include a rectangular portion with the first and second sides being opposite sides of the rectangular portion. The focused ion beam can comprise a gallium ion beam. Magnetic recording heads having a magnetic structure fabricated according to the method are also included.
