1. A data storage device, comprising:
at least one head configured to access a magnetic tape;
one or more reels configured to wind and unwind the magnetic tape;
one or more motors configured to actuate the one or more reels; and
control circuitry configured to:
receive a read or write request;
determine a first distance from a middle of the magnetic tape to a location on the magnetic tape for data corresponding to the read or write request;
position the magnetic tape to allow for an acceleration length to be traveled before reaching the location, wherein the acceleration length is greater than the first distance;
accelerate the magnetic tape over the acceleration length; and
perform the read or write request.
