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 ...
A common practice with single-sided floppies was to punch a second notch on the opposite side of the disk to enable use of both sides of the media, creating a flippy disk, so called because one originally had to flip the disk over to use the other side. 3 + 1 ⁄ 2-inch floppy disks have a sliding tab in a window on the right side (open ...
KryoFlux consists of a small hardware device, [4] [5] which is a software-programmable FDC system that runs on small ARM-based devices that connects to a floppy disk drive and a host PC over USB, and software for accessing the device. KryoFlux reads "flux transitions" from floppy disks at a very fine resolution. [6]

And if you built a plane 20 or 30 or even 40 years ago, you would use a floppy disk to get information in and out of some of the avionics of that airplane."Persky sells about 500 disks a daybut ...
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 ...
A spacing of 0.05 inch (1.27 mm) is the most usual, allowing for a two-row connector with a pin spacing of 0.1 inch (2.54 mm). These types are used for many types of equipment, in particular for interconnections within an enclosure. For personal computers, this size was used in floppy-disk-drive cables and older or custom Parallel ATA cables.
[12] [7] Magnetic tape and floppy disks are vulnerable to both the deterioration of adhesive holding the magnetic data layer to its backing or the demagnetization of the data layer, commonly called "bit rot"; optical discs are specifically susceptible to physical damage to their readable surface, and to oxidation occurring between improperly ...
