Low moment-high moment write pole with non-magnetic layer for establishing a magnetic path discontinuity between layers of the write pole |
摘要 |
A write pole for a magnetic recording head, such as a perpendicular magnetic recording head, includes a first magnetic layer comprising a material having a first saturation magnetic moment and a second magnetic layer adjacent the first magnetic layer wherein the second magnetic layer comprises a material having a second saturation magnetic moment that is greater than the first saturation magnetic moment. The write pole also comprises a non-magnetic layer between a portion of the first magnetic layer and the second magnetic layer. The non-magnetic layer may be formed between the first magnetic layer and the second magnetic layer adjacent an air-bearing surface of the recording head. A disc drive storage system having a recording head with means for reducing skew sensitivity of the recording head is also disclosed.
