Abstract:
1. A method for setting a servo write head spacing for writing servo tracks on a magnetic tape in a manufacturing environment, the method comprising: receiving, by one or more processors, one or more environmental condition measurements of the manufacturing environment; determining, by the one or more processors, a spacing for a pair of servo write heads based at least on: a nominal spacing for the pair of servo tracks; a difference between one or more nominal environmental conditions associated with the nominal spacing and corresponding one or more of the environmental condition measurements of the manufacturing environment; and one or more coefficients of expansion for the magnetic tape; and setting the spacing for the pair of servo write heads to the determined spacing; whereby the spacing of the pair of servo write heads is substantially the nominal spacing when the one or more manufacturing environment environmental condition measurements are the one or more nominal environmental conditions.
