SLANTED BUMP DESIGN FOR MAGNETIC SHIELDS IN PERPENDICULAR WRITE HEADS AND METHOD OF MAKING SAME
摘要:
Embodiments provide a slanted bump magnetic shield in a perpendicular write head and a method of making the shield. The slanted bump magnetic shield provides a small throat height to maximize magnetic flux for writing to a magnetic media such as a magnetic storage disk in a hard disk drive, while avoiding saturation. An etch process is used to form a taper in non-magnetic gap material. The magnetic shield is then deposited on the taper, forming the slanted bump of the shield. The etch process may be a multiple etch process to provide better edge and thickness control when forming the taper.
