摘要：
A method for fabricating a magnetic transducer having an air-bearing surface (ABS) is provided. The method comprises providing an underlayer, and providing a main pole residing on the underlayer and having a front and a rear. The step of providing a main pole further includes providing a first portion having a first magnetic moment, the first portion having a front face at the ABS and terminating between the ABS and the rear of the main pole, and providing a second portion having a second magnetic moment. A part of the second portion resides on the first portion, and another part of the second portion resides between the first portion of the main pole and the rear of the main pole. The first magnetic moment is less than the second magnetic moment.
