ABSTRACT:
A method for adjusting fly heights for a plurality of heads of a hard disk drive is disclosed. The method includes measuring respective magnetic and mechanical performance for the plurality of heads and varying the density of an environment within the hard disk drive. This variation of the environment is such that the respective fly heights of the plurality of heads are adjusted to achieve a preferred distribution with respect to an ideal fly height.
