1-19. (canceled)
A method of using a magnetic head that comprises an air-bearing surface and a transducer, the method comprising:
- testing the magnetic head to measure performance of the magnetic head for use in a first hard disk drive atmosphere that requires a first performance requirement,
- if the magnetic head fails to meet the first performance requirement, testing the magnetic head to measure performance of the magnetic head for use in a second hard disk drive atmosphere that is different from the first hard disk drive atmosphere.
