A method and system provide a magnetic transducer having an air-bearing surface (ABS). The magnetic transducer includes a write pole and at least one coil. The write pole has a pole tip and a yoke. The coil(s) energize the write pole. The coil(s) include a plurality of turns a first distance from the pole and at least one additional turn a second distance from the pole. The first distance is different from the second distance. The at least one additional turn extends over at least part of two of the plurality of turns, has a length in a stripe height direction perpendicular to the ABS and has a height in a down track direction. The length is greater than the height.

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.
摘要:
A magnetic recording transducer for use in a data storage device includes a writer pole with a ABS surface, trailing edge bevel and a trailing shield. The effective throat height of the writer main pole is reduced by the use two gap layers between the writer main pole and the trailing shield. A first gap layer is on and in contact with the writer pole trailing surface, and a second gap layer is on a section of the first gap layer on the writer pole trailing edge bevel, from a point removed from the ABS surface and absent from a part on a section of the first gap layer on the writer pole trailing edge bevel nearest the ABS. A method of fabricating the transducer is also provided.
