Detailed explanation-3: -The platters are made from a non-magnetic material, usually aluminum alloy or glass, and are coated with a thin layer of magnetic material. Older disks used iron(III) oxide as the magnetic material, but current disks use a cobalt-based alloy. A cross section of the magnetic surface in action.

Detailed explanation-4: -A platter is a round magnetic plate that constitutes part of a hard disk. Hard disks typically contain up to a dozen platters.

Detailed explanation-5: -Hard Disk. A hard disk is the primary computer storage medium, which is made of one or more aluminum or glass platters, coated with a ferromagnetic material.
