IBM’s new 3480 cartridge tape system introduced
|
1984 Magnetic tape allows for inexpensive mass storage of information and so is a key part of the computer revolution. Announced in March 1984, IBM’s new 3480 cartridge tape system sought to replace the traditional reels of magnetic tape in the computer center with a 4” x 5” cartridge that held more information (200MB) and offered faster access to it.
BM withdrew the system in 1989 but the new format caught on with other computer makers who began making 3480-compatible storage systems for several years after that, offering increased storage capacity in the same physical format.
