Magnetic recording transducers having slim shaped additional poles

摘要

A magnetic transducer has an air-bearing surface (ABS). The magnetic transducer has a main pole, at least one coil for energizing the main pole and at least one additional pole. The main pole has a yoke and a pole tip having an ABS facing surface. The at least one additional pole is adjacent to the main pole in a down track direction. The additional pole is recessed from the ABS, has a front surface facing the ABS, has at least one side surface, and has at least one flare angle between the front surface and the at least one side surface. The at least one flare angle is measured from the ABS to the at least one side surface and is at least fifty degrees and less than ninety degrees.
