Abstract
A method for writing servo information to a data storage medium adapted for use in a data storage device wherein the medium is operably moved in ambient air at a nominal speed in data reading and writing relationship with a data transfer member. In one embodiment the method for writing comprises placing the medium adjacent a data transfer member in an enclosure containing a gaseous environment as a selected state; moving the medium to impart velocity to the gaseous environment which, in turn, impacts the data transfer member with forces flying the writing member at a first fly height from the medium; and subsequently introducing a gas having a density less than the gaseous environment into the enclosure, thereby responsively reducing the fly height of the writing member to a selected height less than the first fly height.
