Consider a hard disk that rotates at 10 000 rpm. The disk has 1600 cylinders and 32 tracks on each cylinder. The disk is divided into four 400-cylinder zones that contain 360,400, 440 and 480 sectors per track. Each sector contains 1024 bytes. (a) What is the maximum data transfer rate between the disk and the controller's bufer? (b) Determine the disk capacity! (c) How much time is needed to read the data from the entire disk (track per track,sector per sector) if the arm needs 0.5 ms to move to an adjacent cylinder?
