发明名称 Perpendicular magnetic write head with a thin wrap around magnetic shield
摘要 A magnetic write head for perpendicular magnetic recording having a thin wrap-around magnetic shield. The small thickness and forming method of the thin wrap-around magnetic shield allow it to be electroplated using a thin photoresist frame mask. The thin photoresist frame mask has better critical dimension and straight wall control than a thicker mask, which allows the wrap-around magnetic shield to be constructed with much more straight and uniform back edge for shield throat height control than is possible when forming a thicker (i.e. taller) shield. The thin wrap-around magnetic shield can be stitched to a trailing return pole to avoid magnetic saturation of the wrap-around shield.
