magnetic tapes.


Magnetic tapes

They are used for storage. Surface of the tape is magnetic. The tape is coiled onto a reel and can store a lot of data. Magnetic tapes only offer serial access.

If you want data that´s in the middle, you have to forward from the beginning. If you want quick regular access it is better to use a memory stick, a CD, DVD or hard drive.
