摘要：
A perpendicular magnetic recording (PMR) head is fabricated with a pole tip shielded laterally by a graded side shield that is conformal to the shape of the pole tip at an upper portion of the shield but not conformal to the pole tip at a lower portion. The shield includes a trailing shield, that is conformal to the trailing edge of the pole tip and may include a leading edge shield that magnetically connects two bottom ends of the graded side shield.
