(Or TRACk-to-TRACk seek time) The time it takes to move the head of a disk drive from one TRACk to the next. The minimum seek time gives a good measure of the speed of the drive in a single-user/single-process environment where successive read/write request are largely correlated and thus if correlated data is stored in nearby cylinders most seeks are from one cylinder to the next.
