A disk has 800 tracks per surface, 180 sectors per track, and 512 bytes per sector. The disk has 1 surface. The disk rotates at 5000 rpm (rotations per minute). The average seek time between random tracks is 10 ms. The seek time between adjacent tracks is 2 ms. Required:
a. Determine the total storage capacity of the disk.
b. Determine the number of seek operation to read the entire disk.
c. Determine the peak data rate of the disk (MB/second).
d. If the r/w head is at track t, how long will it take to read a sector on track t+1?
