On each side are concentric rings, called tracks, on which a disk can store data. A disk is further divided by sectors, which are similar in shape to pie slices. The - Epson Equity 320SX PLUS | User Manual - Page 60
Your computer uses the read/write heads in a disk drive to store and retrieve data on a disk. To write to a disk, the computer spins it in the drive to position the disk so that the area where the data is to be written is under the read/write head.
