Magnetic write head with flux blockade structure

An apparatus for performing operations on a magnetic recording tape, the apparatus comprising:

• a magnetic head having an array of writers, each writer having a trailing pole piece positioned between a leading pole piece and an upper yoke, the trailing pole piece having a portion adjacent to and extending from a write gap,
• the portion of the trailing pole piece having a throat height (h1) that is about constant along an entire thickness (t1) of the portion of the trailing pole piece in a direction of media motion relative to the trailing pole piece from the write gap to a notch in the trailing pole piece,
• the portion of the trailing pole piece having an aspect ratio of thickness/throat height (t1/h1) in a range of 0.5 and 2,
• wherein the trailing pole piece includes a flare-out extending in a cross-track direction,
• lower surfaces of the flare-out being oriented at an angle (a1) from the cross-track direction,
• the angle (a1) being in a range of from 0 to about 60 degrees,
• the flare out being located a distance(t3) from the write gap;
• wherein the leading pole piece has a throat height dimension (h2) that is greater than h1, and
• wherein the portion of the trailing pole piece has a width (w2) as measured in a cross-track direction that is about constant along the trailing pole piece in the direction of media motion relative to the trailing pole piece for the distance t3.
