However what is Min (Minute), Sec (Second) and Sector fields in Header field? The sectors of CD-ROM aren't arranged like sectors in hard disks (Please see Figure (b)). Rather they are all equal length segments. If we rotate CD drive at constant speed the linear velocity of disk surface movement will be higher at the outer side than that of centre portions. To offset this liner speed gap either we store less data on outer sectors or we decrease speed of rotation while reading outer tracks. CD follows later approach which is instead of moving CD drive at constant velocity. It's rotated at variable velocity. Speed or rotation of disk decreases as we move away from centre such that sector's can be read in constant time. This method of reading is known as Constant Liner Velocity (CLV).
