What is magnetic tape?
Magnetic tape is a medium for magnetic recording, made of a tin magnetizable coating on a long, narow strip of plastic. Most audio, video and computer data storage is this type. It was developed in Germany, based on magnetic wire recording. Devices that record and play back audio and video using magnetic tape are tape recorders and video tape recorders. A device that stores computer data on magnetic tape is a tape drive.(wikipedia)
Floppy disks use magnets to store data, as do most hard drives. The earliest form of disk storage involved magnetic tape on reels. These early disk drives retrieved data more slowly than modern disk drives. Magnetic tape drives still see use even in the most modern of Information Technology departments. The relatively low cost of magnetic tape systems means that IT departments save money by using magnetic computer tape drives.
