NEAR-FIELD TRANSDUCER EFFICIENCY MONITORING SYSTEM |
摘要 |
A system may have a data storage medium that contains at least one data bit that is accessed by a transducing head that has a near-field transducer. A controller can be connected to the transducing head and store a plurality of near-field transducer operating currents in a memory. The controller may identify a change in efficiency of the near-field transducer from the plurality of near-field transducer operating currents. |

1. A method comprising:
connecting a controller to a transducing head having a laser and a near-field transducer; storing a plurality of laser operating currents with the controller; selecting a selected laser operating current from the plurality of laser operating currents based on a detected minimum bit error rate; and accessing a data bit stored on a data storage medium with the selected laser operating current. |
