Magnetic recording write transducer having an improved sidewall angle profile
摘要:
A method and system provide a magnetic transducer having an air-bearing surface (ABS). The magnetic transducer includes a main pole and at least one coil for energizing the main pole. The main pole includes a pole tip region and a yoke region. The pole tip region includes sidewalls, a bottom and a top wider than the bottom. At least one of the sidewalls forms a first sidewall angle with a down track direction at the ABS and a second sidewall angle with the down track direction at a first distance recessed from the ABS. The first sidewall angle is greater than the second sidewall angle.
