How long does it take to read a disk with 4,000 cylinders, each containing six tracks

of 512 sectors? First, all the sectors of track 3999 are to be read starting at ANY SECTOR, then

all the sectors of track 3998 starting at ANY SECTOR, and so on. The rotation time is 8 msec,

and a seek takes 2 msec between adjacent cylinders and 30 msec for the worst case.

Switching between tracks of a cylinder can be done in 1 msec.
