Answer:

Platter

Explanation::

Hard drives are normally composed of Multiple disks called Platters. These Platters are stacked on top of each other. It is the Platter that actually stores the data. It consists of a substrate coated with magnetic media. The substrate is there to act as a rigid support for the magnetic media. The magnetic layer is protected by a thin layer of carbon and a lubrication layer to prevent damage in case the head comes in contact with the platter surface.

Typically, both sides of the Platter have magnetic media on which to store data. Tens of thousands of tracks per inch can be laid down on these platters.
