| 发明名称 | Magnetic element with biased side shield lamination | ||
| 摘要 | A magnetic element is generally provided that can be implemented as a transducing head. Various embodiments may configure a magnetic stack having a magnetically free layer with a predetermined magnetization. A side shield lamination can be separated from the magnetic stack on an air hearing surface (ABS) and biased to a bias magnetization that opposes the predetermined magnetization. | ||

| 主权项 | 1. An apparatus comprising a magnetic stack having a first magnetically free layer with a predetermined magnetization, and a side shield lamination separated from the magnetic stack on an air bearing surface (ABS), configured with a first width on the ABS, and biased to a bias magnetization that opposes the predetermined magnetization by a shield bias feature contacting the side shield lamination with a second width on the ABS without contacting the magnetic stack, the first and second widths measured parallel to the predetermined magnetization and the first width being greater than the second width. | ||
