A double notched magnetic structure for use in a magnetic head for
avoiding stray field writing. The structure could be a magnetic shield,
magnetic pole of a write head or some other magnetic structure used in a
magnetic head of a magnetic recording system, and has notches formed at
both the front end (adjacent to the ABS) and at the back end (away from
the ABS). The notches at the front end form a forward protruding portions
that performs the necessary function of the structure, such as magnetic
shielding, and has laterally extending recessed portions (recessed by the
front notches) that move the flux focal points of the structure away from
the ABS to avoid stray field writing. The back notches form a backward
extending portion that affects the geometry of the structure to prevent
the focusing of magnetic flux caused by stray magnetic fields having a
component perpendicular to the ABS.
