The invention provides a perpendicular write head having a stepped flare structure and method of manufacture thereof. The magnetic write head for data recording having a magnetic write pole with a stepped magnetic shell structure that defines a secondary flare point. The secondary flare point defined by the magnetic shell portion can be more tightly controlled with respect to its distance from the air bearing surface (ABS) of the write head than can a traditional flare point that is photolithographically on the main pole structure. This allows the effective flare point of the write head to bemoved much closer to the ABS than would otherwise be possible using currently available tooling and photolithography techniques. The write head may also include a magnetic trailing shield that wraps around the main pole portion. The trailing shield can have a hack edge defining a trailing shield throat height that is either between the secondary flare point or coincident or behind the secondary flare point, depending on design requirements.
