6.3 a. Capacity = 8*512*64*1KB = 256 MB
b. Rotational latency = rotation_time/2 = 60/(3600*2)=8.3ms.
Average access time = seek time + rotation latency = 16.3 ms.
c. Each cylinder consists of 8 track *64 sectors/track *1KB/sector =512 KB, so 5 MB requires exactly 10 cylinders.
The disk will need the seek time of 8 ms to find cyliner i,8.3 ms on average to find sector 0, and 8*(60/3.6) = 133.3 ms to read all 8 tracks on one cylinder.
Then, the time needed to move to the next adjoining cylinder is 1.5 ms, which is the track-to-track access time.
Assume a rotational latency before each track.
Access time =
d. Burst rate =
