Method and system for providing a magnetic recording transducer having a hybrid moment pole

A magnetic transducer having an air-bearing surface (ABS) comprising:

• an underlayer;
• a main pole residing on the underlayer and having a front and a rear, the front at the ABS and the rear distal from the ABS, the main pole also including a first portion and a second portion, the first portion including at least one layer, each of the at least one layer having a magnetic moment greater than the magnetic moment of a lower layer of the at least one layer, the second portion having a second portion magnetic moment, the first portion having a front face at the ABS and terminating between the ABS and the rear of the main pole, a part of the second portion residing on the first portion, another part of the second portion residing between the first portion of the main pole and the rear of the main pole such that a line normal to the ABS passing through the first portion also passes through the other part of the second portion of the main pole, the magnetic moment of a top layer of the plurality of layers being at least one Tesla and not more than 2 Tesla, the second moment being greater than two Tesla, the first portion terminating at least fifty nanometers and not more than two hundred nanometers from the ABS.

A disk drive comprising:

• a slider;
• a magnetic transducer coupled with the slider and having an air-bearing surface (ABS), the magnetic transducer including an underlayer and a main pole residing on the underlayer, the main pole having a front and a rear, the front at the ABS and the rear distal from the ABS, the main pole also including a first portion having a first magnetic moment and a second portion having a second magnetic moment, the first portion having a front face at the ABS and terminating between the ABS and the rear of the main pole, a part of the second portion residing on the first portion, another part of the second portion residing between the first portion of the main pole and the rear of the main pole such that a line normal to the ABS passing through the first portion also passes through the other part of the second portion of the main pole, the first magnetic moment being less than the second magnetic moment.
