PERPENDICULAR MAGNETIC RECORDING HEAD WITH A MULTILAYERED MAIN WRITE POLE

摘要

A perpendicular magnetic recording head (22) includes a multilayered main write pole (30). The main write pole (30) includes a first layer of material (46), a second layer of material(48), and an interlayer (50) positioned between the first layer of material (46) and the second layer of material (48). The second layer of material (48) has a saturation magnetic moment greater than a saturation magnetic moment of the first layer of material (46).
