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 ...
Floppy disks remained a popular medium for nearly 40 years, but their use was declining by the mid- to late 1990s. [4] After 2000, floppy disks were increasingly rare and used primarily with older hardware, especially with legacy industrial and musical equipment. [5] Sony manufactured its last new floppy disks in 2011. [6]
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 is not rewritable and lacks most elements of the IBM floppy disk patent.
Each side of the disk had 46 tracks, and the number of sectors per track varies from 15 to 22. This results in 851 sectors per side, or a total capacity of 871,424 bytes. [ 5 ] The Lisa Hardware Manual doesn't explicitly state the total number of sectors, but page 173 states that there are 4 tracks of 22 sectors, 7x21, 6x20, 6x19, 6x18, 6x17 ...
