Methods and devices for controlling asymmetry in a magnetic reader |
| 摘要 |
In certain embodiments, an apparatus includes a magnetoresistive (MR) sensor having a first and second electrode positioned at a first side of the MR sensor and a third electrode positioned at a second side of the MR sensor opposite the first side. In certain embodiments, an apparatus includes first and second electrodes coupled to an MR sensor and positioned at a first side of the MR sensor. The first and second electrodes are spaced apart from each other and are positioned over an area of the MR sensor that has a positive or negative asymmetry. |

1. A device comprising:
a magnetoresistive (MR) sensor having areas of positive or negative asymmetry; and first and second electrodes coupled to the MR sensor and positioned at a first side of the MR sensor, wherein the first and second electrodes are spaced apart from each other and are positioned over an area of the MR sensor that has a positive or negative asymmetry such that the MR sensor's asymmetry becomes more balanced. |
