The Bernoulli Box was a mass storage device of the 1980s developed by the Iomega company and named after the Swiss physicist Daniel Bernoulli. Daniel Bernoulli lived in the 18th century and was the first to prove the principle of aerodynamic lifting force, which was implemented in the Bernoulli Box. In this process, a flexible magnetic disk rotates at a high rotational speed and is thus pushed upwards to the read/write heads arranged above the magnetic disk, which have a distance of only 0.2 µm above the magnetic disk.
The Bernoulli box itself was a removable disk system for permanent data storage. The magnetic disks were flexible, comparable to floppy disks, and housed in special cartridges. The rotation speed of the flexible magnetic disks was 3,000 revolutions per second, storage capacities ranged from 20 MB to 200 MB, and access times were 10 ms.
