5. (20 pts) How long does it take to read a disk with 600 cylinders, each containing four tracks of 32 sectors? First, all the sectors of track 0 are to be read starting at sector 0, then all the sectors of track 1 starting at sector 0, and so on. The rotation time is 15 msec, and a seek takes 5 msec between adjacent cylinders and 50 msec for the worst case. S witching between tracks of a cylinder can be done instantaneously
