The most popular system was the Bernoulli Box II, whose disk cases are 13.6 cm wide, 14 cm long and 0.9 cm thick, somewhat resembling a 5¼-inch standard floppy disk. The disks came in the following capacities: 20 MB, 35 MB, 44 MB, 65 MB, 90 MB (late 1980s), 105 MB, 150 MB, and in 1993, 230 MB. There are five types of drives, grouped by the ...
The original Zip disk's 100MB capacity was a huge improvement over the decades-long standard of 1.44MB standard floppy disks. ... July, Shipped Bernoulli Box 90 MB ...
The 250 MB drive writes much more slowly to 100 MB disks than the 100 MB drive, and the Iomega software is unable to perform a "long" (thorough) format on a 100 MB disk (They can be formatted in any version of Windows as normal; the advantage of the Iomega software is that the long format can format the 100 MB disks with a slightly higher ...
Storage Module Drive (SMD) is a family of storage devices (hard disk drives) that were first shipped by Control Data Corporation in December 1973 as the CDC 9760 40 MB (unformatted) storage module disk drive. [1] The CDC 9762 80 MB variant was announced in June 1974 [1] and the CDC 9764 150 MB and the CDC 9766 300 MB variants were announced in ...
The Bernoulli's principle main article is generally and specifically useless, so these matters need to be addressed in this article. BBC News 2006: 'Without Daniel Bernoulli we would not have a name for the effect that we rely on to make the hard disk work. The Bernoulli Effect is what happens when a wing moves through the air - it floats.
1962 – IBM 1311 introduced removable disk packs containing 6 disks, storing 2 million characters per pack; 1964 – IBM 2311 with 7.25 megabytes per disk pack; 1964 – IBM 2310 removable cartridge disk drive with 1.02 MB on one disk; 1965 – IBM 2314 with 11 disks and 29 MB per disk pack; 1968 – Memorex is first to ship an IBM-plug ...
The ST-506 and ST-412 (sometimes written ST506 and ST412 [1]) were early hard disk drive products introduced by Seagate in 1980 and 1981 respectively, [1] that later became construed as hard disk drive interfaces: the ST-506 disk interface and the ST-412 disk interface. Introduced in 1980, the ST-506 was the first 5.25 inch HDD.
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 ...
