magnetic storage
Hard drive technology
Magnetic storage is a method of recording data by magnetizing particles on a surface—tape, disk, or drum.
Hard drives, floppy disks, and cassette tapes all use magnetic storage.
The technology dominated computing for decades: The old mainframe relied on magnetic storage.
It contrasts with optical storage (CDs, DVDs) and solid-state storage (flash drives, SSDs).
