A number of solutions were developed, with drives at 2-, 2 1⁄ 2-, 3-, 3 1⁄ 4-, 3 1⁄ 2- and 4-inches (and Sony's 90.0 mm × 94.0 mm disk) offered by various companies. Originally designed to be more practical than the 8-inch format, it was itself too large as the quality of recording media grew, data could be stored in a smaller area. Throughout the early 1980s, limitations of the 5 1⁄ 4-inch format became clear. In 1988 IBM introduced a drive for 2.88 MB "DSED" (Double-Sided Extended-Density) diskettes in its top-of-the-line PS/2 models, but this was a commercial failure.

These disk drives could be added to older PC models. IBM started using the 720 KB double-density 3 1⁄ 2-inch microfloppy disk on its Convertible laptop computer in 1986 and the 1.44 MB high-density version with the PS/2 line in 1987. In 1984 IBM introduced with its PC-AT model the 1.2 MB dual-sided 5 1⁄ 4-inch floppy disk, but it never became very popular. The most common capacity of the 5 1⁄ 4-inch format in DOS-based PCs was 360 KB, for the DSDD (Double-Sided Double-Density) format using MFM encoding. The 5 1⁄ 4-inch format displaced the 8-inch one for most applications, and the hard-sectored disk format disappeared. There were competing floppy disk formats, with hard- and soft-sector versions and encoding schemes such as FM, MFM, M 2FM and GCR. By 1978 there were more than 10 manufacturers producing such FDDs.
In 1976, Shugart Associates introduced the 5 1⁄ 4-inch FDD. The term "floppy disk" appeared in print as early as 1970, and although IBM announced its first media as the "Type 1 Diskette" in 1973, the industry continued to use the terms "floppy disk" or "floppy". These disks and associated drives were produced and improved upon by IBM and other companies such as Memorex, Shugart Associates, and Burroughs Corporation. The first commercial floppy disks, developed in the late 1960s, were 8 inches (200 mm) in diameter they became commercially available in 1971 as a component of IBM products and then were sold separately beginning in 1972 by Memorex and others.

While floppy disk drives still have some limited uses, especially with legacy industrial computer equipment, they have been superseded by data storage methods with much greater capacity, such as USB flash drives, flash storage cards, portable external hard disk drives, optical discs, and storage available through computer networks such as cloud storage.

The prevalence of floppy disks in late 20th century culture was such that many electronic and software programs still use the floppy disks as save icons. These formats are usually handled by older equipment.
By 2006 computers were rarely manufactured with installed floppy disk drives 3 1⁄ 2-inch floppy disks can be used with an external USB floppy disk drive, but USB drives for 5 1⁄ 4-inch, 8-inch, and non-standard diskettes are rare to non-existent. Floppy disks are read and written by a floppy disk drive ( FDD).įloppy disks, initially as 8-inch (203 mm) media and later in 5 1⁄ 4-inch (133 mm) and 3 1⁄ 2 inch (90 mm) sizes, were a ubiquitous form of data storage and exchange from the mid-1970s into the first years of the 21st century.
