Abstract
A method for improving the magnetic performance of at least one magnetic transducer operating within a hard disk drive. The method comprises flying the magnetic transducer at a distance of separation from a magnetic recording media. The magnetic transducer is coupled with a highly damped air bearing surface and a fly height control device. At least one operating parameter of the hard disk drive is measured. The magnetic transducer is moved with the fly height control device into contact with the magnetic recording media, in accordance with at least one operating parameter of the hard disk drive. The magnetic transducer is operated while the magnetic transducer is in contact with the magnetic recording media, thereby improving the magnetic performance of the magnetic transducer.
