Bernoulli Box (redirected from Iomega Bernoulli Box)

Bernoulli Box

An early removable disk drive from Iomega. Introduced in 1983 with 10MB cartridges containing an 8" floppy platter, the Bernoulli provided an extremely reliable, removable and high capacity (for the time) storage medium for early personal computers. In the late 1980s, 5.25" drives were introduced with 20, 44 and 90MB capacities. Later a MultiDisk Bernoulli accepted cartridges up to 150MB, and by 1994, capacity was up to 230MB.

Unlike a hard disk in which the read/write head flies over a rigid disk, the Bernoulli floppy is spun at high speed and bends up close to the head. Upon power failure, a hard disk must retract the head to prevent a crash, whereas the Bernoulli disk naturally bends down. See Bernoulli's principle and magnetic disk.

Bernoulli Cartridge

This is an example of a third-generation Bernoulli cartridge. The Bernoulli was the first removable storage for personal computers, which proved very reliable.
