Abstract:
A method for fabricating a dual element head for use in transferring data to and from a recording medium, said dual element head having both a read element and a write element, wherein said write element defines a write width and said read element defines a read width, said method comprising the steps of:first depositing a first head element upon a substrate, said first head element being one of said read element and said write element, and said step of first depositing having a first tolerance;second depositing a second head element upon said first head element, said second head element being the other of said read element and said write element, and said step of second depositing having a second tolerance, that is independent of said first tolerance, wherein the functional width of said second head element is made wider than a desired functional width for said second head element during said step of second depositing; andtrimming said second head element to substantially achieve said desired functional width while using a portion of said first head element as a reference to reduce errors associated with the independent nature of said first and second tolerances.
