Open Reels
Initially, magnetic tape for data storage was wound on large (10.5 in/26.67 cm) reels. This defacto standard for large computer systems persisted through the late 1980s. Tape cartridges and cassettes were available as early as the mid 1970s and were frequently used with small computer systems. With the introduction of the IBM 3480 cartridge in 1984, large computer systems started to move away from open reel tapes and towards cartridges.

Famous quotes containing the word open:
“The attempt to be an ideal parent, that is, to behave correctly toward the child, to raise her correctly, not to give to little or too much, is in essence an attempt to be the ideal child—well behaved and dutiful—of one’s own parents. But as a result of these efforts the needs of the child go unnoticed. I cannot listen to my child with empathy if I am inwardly preoccupied with being a good mother; I cannot be open to what she is telling me.”
—Alice Miller (20th century)
