Company: UNIVAC, IBM, Digitral...
Launched: 1950
Capacity:

Large computers of the late 1980s used magnetic tapes wound onto large (10.5-inch) reels for storage.

Magnetic tape was the medium used for the first computer recording in 1951 on the Eckert-Mauchly UNIVAC I, the first computer commercially manufactured in the United States.
IBM computers of the 1950s used ferric oxide-coated tape similar to that used in audio recording, which soon became the industry standard.
The latest versions of reel-to-reel data storage systems had a capacity and data transfer rate similar to floppy disks, which would eventually displace them from the market, but their seek times were on the order of 30 seconds to one minute.
The handicap they faced was that tapes, unlike disks, are a sequential access medium.
