Which device uses magnetic storage on spinning platters to store data?

• A. Flash Drive
• B. Optical Disc
• C. Hard Drive
• D. RAM

Answer: (C)

Magnetic storage on spinning platters involves data being stored as magnetized regions on the surface of spinning disks. A read/write head hovers over the surface and alters or detects the magnetization as the platters rotate, allowing access to different areas (tracks and sectors) of the disk. This setup is how a hard drive stores large amounts of data with moving parts. In contrast, flash drives use solid-state memory with no moving parts, optical discs rely on a laser to read physical pits, and RAM is fast volatile memory used for temporary data. So the device that uses magnetic storage on spinning platters to store data is the hard drive.
