Explain the relationship among disk platters, tracks, sectors, and clusters.

Hard disks are made from one or more platters made from metal or glass disks. Each platter contains a head on it and each head is moved by a finer motor or a magnetic driver one step at a time to each track. A track is like a magnetic ring and each ring is made up of sectors. A cluster writes or reads data from disk in chunks of sectors. A cluster includes sectors from two heads.
