Magnetic recording writer having a main pole with multiple flare angles |
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 first portion and a second portion. The first portion includes a pole tip and at least one side surface. The pole tip has an ABS facing surface at the ABS. The first portion has a first flare angle between the ABS and a side surface. The second portion is on the first portion and recessed from the ABS. The second portion has a second flare angle greater than the first flare angle. The first portion is wider in a cross track direction than the second portion. |
