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; they became commercially available in 1971 as a component of IBM products and both drives and disks were then sold separately ...
8-inch, 5¼-inch, and 3½-inch floppy disks. A floppy disk is a disk storage medium composed of a thin and flexible magnetic storage medium encased in a rectangular plastic carrier. It is read and written using a floppy disk drive (FDD). Floppy disks were an almost universal data format from the 1970s into the 1990s, used for primary data ...
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. 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 ...
IBM manufactured 8-inch floppy disk drives from 1969 until the mid-1980s, but did not become a significant manufacturer of smaller-sized, 5.25- or 3.5-inch floppy disk drives (the dimension refers to the diameter of the floppy disk, not the size of the drive).
Floppy disk drive interface. Each generation of floppy disk drive (FDD) began with a variety of incompatible interfaces but soon evolved into one de facto standard interface for the generations of 8-inch FDDs, 5.25-inch FDDs and 3.5-inch FDDs. [1] For example, before adopting 3.5-inch FDD standards for interface, media and form factor there ...
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]
Most floppy disks used by PCs use the FAT12 file system format, which imposes certain practical defaults on the logical geometry in order to be recognizable by all operating systems. Sometimes disks may use a more exotic file system. SSDD originally referred to Single Sided, Double Density, a format of (usually -inch) floppy disks which could ...
Sony Digital Mavica MVC-FD5 (1997), the first digital camera of the Mavica series. Mavica ( Magnetic Video Camera) is a discontinued brand of Sony cameras which use removable disks as the main recording medium. On August 25, 1981, Sony unveiled a prototype of the Sony Mavica as the world's first electronic still video camera.
