摘要：
A method and system provide a magnetic transducer that includes an air-bearing surface (ABS). The magnetic transducer includes an underlayer and a main pole residing on the underlayer. The main pole includes a front and a rear. The front resides at the ABS, while the rear is distal from the ABS. The main pole also includes a first portion having a first magnetic moment and a second portion having a second magnetic moment. The first portion has a front face at the ABS and terminates between the ABS and the rear of the main pole. A part of the second portion resides on the first portion, while 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.
