DYNAMICALLY OPTIMIZING READ PERFORMANCE BY ADJUSTING SERVO-BASED HEAD LOCATION |
摘要 |
A computer-implemented method includes: determining a reading performance of a head positioned at a commanded lateral reading location based on one or more metrics; adjusting a lateral reading location of the head relative to a medium by moving the head in a lateral direction away from the commanded lateral reading location to an adjusted lateral reading location; determining a reading performance of the head after the adjusting; comparing the reading performance after the adjusting to the reading performance before the adjusting for determining whether the reading performance has improved; and selecting an optimal lateral reading location based on the comparing. The one or more metrics are selected from a group consisting of C1 error correction rate, and C2 error correction rate. Corresponding systems and computer program products are also disclosed. |

1. A computer-implemented method, comprising:
determining a reading performance of a head positioned at a commanded lateral reading location based on one or more metrics; adjusting a lateral reading location of the head relative to a medium by moving the head in a lateral direction away from the commanded lateral reading location to an adjusted lateral reading location; determining a reading performance of the head after the adjusting; comparing the reading performance after the adjusting to the reading performance before the adjusting for determining whether the reading performance has improved; selecting an optimal lateral reading location based on the comparing; and wherein the one or more metrics are selected from a group consisting of C1 error correction rate, and C2 error correction rate. |
