The world's first 5.25-inch floppy drive was developed by Shugart Associates in 1976 for IBM's mainframe. It was later used in IBM's early PCs. In 1980, Sony introduced a 3.5-inch disk. By the early 90's, 3.5-inch, 1.44-MB floppy disks have been used for standard data transmission methods for PCs.
Early computers generally used a 5.25-inch floppy drive, and there were two main 5.25-inch floppy drives. A 5.25-inch double-sided high-density floppy drive (also known as 5.25-inch 1.2M floppy drive), can read and write 5.25-inch double-sided high-density floppy disk (1.2M), 5.25-inch double-sided low density floppy disk (360K), 5.25 inches single low density Floppy disk (180K). The other is a two-sided low density floppy drive, the main difference with the former is the inability to read and write 5.25 inches double-sided high density floppy disk (1.2M). Later it produced a 3.5-inch double-sided high-density floppy drive (also known as 3.5-inch 1.44M floppy drive), and can read and write 3.5-inch double-sided high-density floppy disk (1.44M) and 3.5-inch single-sided high-density floppy disk (720K). For a long time, the computer generally has two floppy drives, which are respectively a 5.25-inch 1.2M floppy drive and a 3.5-inch 1.44M floppy drive. Now it is generally only equipped with a 3.5-inch 1.44M floppy drive.
The common floppy drive is characterized by small capacity, high cost per unit of capacity, floppy disk error-prone, poor reliability, and slow speed. Notebooks generally use built-in 3.55" 1.44MB floppy or external floppy drive.
