Monitoring a fly height of a magnetic transducer |
摘要 |
A method for monitoring a fly height of a magnetic transducer comprises flying the magnetic transducer at a distance of separation from a recording media. A read-back signal is read with the magnetic transducer from the recording media. The read-back signal is rectified to produce a rectified signal. The rectified signal is filtered thereby providing a filtered signal. A fault signal is provided in response to the filtered signal exceeding a threshold.
