Track to track seek time is the time that head of a disk takes to move from one track to adjacent track. It is involved mostly in sequential operations on disk. If I/O operations are submitted to disk at a fast speed then track to track seek time is less and I/O becomes efficient but it is ideal case and does not occurs mostly and disk platter spins among this time. Track to track seek time of a disk has no dependence on fact that how you have mapped data files to disk. It depends entirely on design and performance of your disk controller.
