Area density on storage media refers to the amount of data per which metric?

• A. The Amount Of Data Per Partition
• B. The Amount Of Data Per Disk
• C. The Amount Of Data Per Square Inch
• D. The Amount Of Data Per Platter

Answer: (C)

Area density, or areal density, measures how much data is stored on a given area of the storage surface. It is the amount of data per unit area, usually expressed as bits per square inch (or bytes per square inch). This density combines how closely data is packed along each track (linear density) with how many tracks fit into a given area (track density). Higher areal density means more data in the same physical space. It’s not about data per partition, per disk, or per platter, which describe total data or capacity rather than how densely that data is packed on the surface.
