The original Bernoulli Alpha drive spins a PET film floppy disk at about 1500 rpm, [1] 1 μm over a read-write head, using Bernoulli's principle to pull the flexible disk towards the head as long as the disk is spinning. In theory this makes the Bernoulli drive more reliable than a contemporary hard disk drive, since a head crash is impossible.
A Maxell-branded 3-inch Compact Floppy Disk. The floppy disk is a data storage and transfer medium that was ubiquitous from the mid-1970s well into the 2000s. [1] Besides the 3½-inch and 5¼-inch formats used in IBM PC compatible systems, or the 8-inch format that preceded them, many proprietary floppy disk formats were developed, either using a different disk design or special layout and ...
Iomega Corporation (later LenovoEMC) [3] [4] [5] was a company that produced external, portable, and networked data storage products. Established in the 1980s in Roy, Utah, United States, Iomega sold more than 410 million digital storage drives and disks, including the Zip drive floppy disk system. [6]
"As the disk spins this lifts the head up off the media," explained Ian Keene of hard drive manufacturers WD. He added: "Many people think the head is actually touching the media, but the distance between the head and the media is in the distance of 100 angstroms; to give you some idea of what an angstrom is, a human hair is about one million ...
The Zip drive is a "superfloppy" disk drive that has all of the standard 3 + 1 ⁄ 2-inch floppy drive's convenience, but with much greater capacity options and with performance that is much improved over a standard floppy drive. However, Zip disk housings are similar to but slightly larger than those of standard 3 + 1 ⁄ 2-inch floppy disks ...

DEC was both a manufacturer and a buyer of magnetic disk storage, offering more than 100 different models of hard disk drive (HDD) and floppy disk drive (FDD) during its existence. [89] In the 1970s, it was the single largest OEM purchaser of HDDs, procuring from Diablo , Control Data Corporation , Information Storage Systems, and Memorex ...
The Xerox 6060 came standard with a single 360 KB 5.25" drive and a 20 MB hard drive. An Iomega Bernoulli 10/10 removable cartridge drive was also offered as a factory option, as well as a "small expansion" sidecar hosting a hard drive for users who found themselves with no internal space left between floppies and expansion cards.
