| 发明名称 | Read sensor with free layers of different widths sandwiching a SAF structure for extremely high resolution | ||
| 摘要 | A read sensor that includes an air bearing surface and a synthetic antiferromagnetic (SAF) structure. The read sensor also includes a first free layer (FL) above the SAF structure and a second FL below the SAF structure. The first FL and the second FL have differing widths at the bearing surface. The first FL, the second FL and the SAF structure are configured to provide a reader resolution that corresponds to a difference between a first width of the first FL and a second width of the second FL. | ||

| 主权项 | 1. A read sensor comprising: a bearing surface; a synthetic antiferromagnetic (SAF) structure; a first free layer (FL) above the SAF structure; and a second FL below the SAF structure; wherein the first FL and the second FL have differing widths at the bearing surface, and wherein the first FL, the second FL and the SAF structure are configured to provide a reader resolution that corresponds to a difference between a first width of the first FL and a second width of the second FL. | ||
