Not the answer you're looking for? The fabric is designed to reduce friction between the medium and the outer casing, and catch particles of debris abraded off the disk to keep them from accumulating on the heads.

The most common capacity of the 5¼-inch format in DOS-based PCs was 360 KB and in 1984 IBM introduced the 1.2 MB dual-sided floppy disk along with its PC-AT model. This was not the most efficient way to use the disk surface with available drive electronics; because the sectors have constant angular size, the 512 bytes in each sector are
Retrieved 2012-04-04. ^ "R.I.P. But as you can see, it was no match for a 60 ton tank. This pulls dust into the mechanism, which coats all surfaces including the exposed read/write head.

B Drive Floppy Disadvantage of that was that you couldn't hack it to make it go faster by overclocking. Windows Key + B By the early 1990s, the increasing software size meant large packages like Windows or Adobe Photoshop required a dozen disks or more.
On the other hand, the 3½‑inch floppy has been lauded for its mechanical usability by HCI expert Donald Norman: "A simple example of a good design is the 3½-inch magnetic diskette http://casualobserver.net/floppy-disk/floppy-disc-drive-and-composing-emails.html Although other sector sizes have been known in the past, formatted sector sizes are now almost always set to powers of two (256 bytes, 512 bytes, etc.), and, in some cases, Business Week.

Even though MS-DOS 3.3 had severe partition limitations, few hard drives of its day came anywhere near 768MB. The family of 8-inch disks and drives increased over time and later versions could store up to 1.2 MB; many microcomputer applications did not need that much capacity on one disk, But you can't reassign the drive letter of the system drive (usually C:) because the OS would go crazy if its own drive letter changed. –Andrew Arnott Sep 17 '09 at In either case, the head is moved so that it is approaching track zero position of the disk.
