The 3 + 1 ⁄ 2-inch disks had, by way of their rigid case's slide-in-place metal cover, the significant advantage of being much better protected against unintended physical contact with the disk surface than 5 + 1 ⁄ 4-inch disks when the disk was handled outside the disk drive. When the disk was inserted, a part inside the drive moved the ...
8-inch floppy disk, inserted in drive, (3½-inch floppy diskette, in front, shown for scale) 3½-inch, high-density floppy diskettes with adhesive labels affixed The first commercial floppy disks, developed in the late 1960s, were 8 inches (203.2 mm) in diameter; [4] [5] they became commercially available in 1971 as a component of IBM products and both drives and disks were then sold ...
The 21 MB Floptical 3 + 1 ⁄ 2-inch disk. Floptical refers to a type of floppy disk drive that combines magnetic and optical technologies to store data on media similar to standard 3 + 1 ⁄ 2-inch floppy disks. The name is a portmanteau of the words "floppy" and "optical". It refers specifically to one brand of drive and disk system, but is ...
An IBM spokesman, Mac Jeffery, confirmed that the company did license some of his patents, but said that they were not for the floppy disk, which he said IBM invented on its own. [28] Another IBM spokesman, Brian Doyle, said that the company licensed 14 patents from Nakamatsu and those patents do not have anything to do with the floppy disk.
Double density (DD) 3½-inch disks use an iron oxide coating, just as with 5¼-inch DD/QD disks. However, drives utilize stronger 670-oersted write heads and a narrower track width of 0.115 mm (0.0045 in) for a density of 135 tpi and 8,717 bpi. High density (HD) 3½-inch disks switch to a cobalt disk coating, just as with 5¼-inch HD disks ...
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 ...
It was in competition with a similar product by IBM that had an external floppy disk drive. The assembly line was located in the Olivetti factories of Scarmagno , some modules forming subsets of the machine as a printer or floppy disks were manufactured at plants in San Bernardo d'Ivrea .
A number of similar models were released, not marketed by Atari, mainly in Eastern Europe and Latin America, including these: [13] XCA12 (same case as XC12) CA12 (same case as XC12) XL12 tape drive (an XC12 with minor changes) XF551 Disk Drive - 5¼" floppy disk, double-density double-sided, 360 KB; XMM801 Dot-Matrix Graphics Printer - 80-column
