Non-decision directed magnetoresistive asymetry estimation |
| 摘要 |
Systems and methods for magnetoresistive asymmetry estimation may include, but are not limited to, operations for: receiving a magnetic read head transducer output; computing a mean value of the magnetic read head transducer output; computing a median value of the magnetic read head transducer output; and applying a correction coefficient to a magnetic read head detector input according to at least the mean value of the magnetic read head transducer output and the median value of the magnetic read head transducer output. |

1. A computing-device implemented method comprising:
receiving a magnetic read head transducer output; computing a mean value of the magnetic read head transducer output; computing a median value of the magnetic read head transducer output, wherein the computing a median value of the magnetic read head transducer output includes:
receiving a current estimate of the median value of the magnetic read head transducer output;comparing the current estimate of the median value of the magnetic read head transducer output to the magnetic read head transducer output; andgenerating an updated estimate of the median value of the magnetic read head transducer output according to the comparison; and applying a correction coefficient to a magnetic read head detector input according to at least the mean value of the magnetic read head transducer output and the median value of the magnetic read head transducer output. |
