Magnetic transducer for perpendicular magnetic recording with single pole write head with trailing shield

A thin film magnetic recording head for perpendicular recording comprising:

• a yoke that includes a main pole piece that extends to an air-bearing surface and a return pole piece that extends to an air-bearing surface;
• a coil that passes through the yoke between the main pole piece and the return pole piece;
• and
• a trailing shield with a pedestal and a tip, the pedestal being connected to the return pole piece and extending along the air-bearing surface toward the main pole piece, the tip being attached to the pedestal and confronting the main pole piece to form a write gap with a length along the air-bearing surface that is less than a thickness of the coil between the main pole piece and the return pole piece, the tip having a cross-section area orthogonal to the air-bearing surface which is smaller than a cross-section area of the pedestal orthogonal to the air-bearing surface.

A thin film magnetic recording head for perpendicular recording comprising:

• a yoke that includes flux bearing pole piece, a main pole piece attached to the flux bearing pole piece that extends to an air-bearing surface and a return pole piece that extends to an air-bearing surface;
• a coil that passes through the yoke between the main pole piece and the return pole piece;
• a trailing shield with a pedestal and a tip, the pedestal being connected to the return pole piece and extending along the air-bearing surface toward the main pole piece, the tip being attached to the pedestal and confronting the main pole piece to form a write gap with a length along the air-bearing surface that is less than a thickness of the coil between the main pole piece and the return pole piece, the tip having a cross-section area orthogonal to the air-bearing surface which is smaller than a cross-section area of the pedestal orthogonal to the air-bearing surface and tip having a cross-track width that is approximately equal to a cross-track width of the main pole piece at the air-bearing surface;
• a read head with first and second read shields with the second read shield being separated from the flux bearing pole piece by a separation gap;
• and
• a sink of non-magnetic, electrically conductive material disposed in the separation gap.
