Magnetic writer having a low aspect ratio two layer coil
Abstract:
A method and system provide a magnetic transducer having an air-bearing surface (ABS). The magnetic transducer includes a write pole and at least one coil. The write pole has a pole tip and a yoke. The coil(s) energize the write pole. The coil(s) include a plurality of turns a first distance from the pole and at least one additional turn a second distance from the pole. The first distance is different from the second distance. The at least one additional turn extends over at least part of two of the plurality of turns, has a length in a stripe height direction perpendicular to the ABS and has a height in a down track direction. The length is greater than the height.
