Shugart Associates (later Shugart Corporation) was a computer peripheral manufacturer that dominated the floppy disk drive market in the late 1970s and is famous for introducing the 5 + 1 ⁄ 4-inch "Minifloppy" floppy disk drive. In 1979 it was one of the first companies to introduce a hard disk drive form factor compatible with a floppy disk ...
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 ...
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 phrase "IBM PC compatible self-booting disk" is sometimes shortened to "PC booter". Self-booting disks were common for other computers as well. These games were distributed on 5 + 1 ⁄ 4 " or, later, 3 + 1 ⁄ 2 ", floppy disks that booted directly, meaning once they were inserted in the drive and the computer was turned on, a minimal ...
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 ...
Like TPI, "double sided" was mostly a certification indicator, as the magnetic media was usually recordable on both sides. Many (but not all) certified "double sided" 8- and 5 + 1 ⁄ 4-inch floppies had an index hole on both sides of the disk sleeve to make them usable as flippy disks. A combination floppy disk and optical disc, known as a ...
3.5-inch and 5.25-inch drives connect to the floppy controller using a 34-conductor flat ribbon cable for signal and control. Most controllers support two floppy drives, although the Shugart standard supports up to four drives attached to a single controller. A cable could have 5.25-inch style connectors, 3.5-inch style connectors, or a ...
