How Disks Store Data Diskettes are made of flexible plastic coated with magnetic material. This plastic is enclosed in a square jacket that is either hard (M-inch diskette) or slightly flexible (5.25-inch diskette). Unlike a diskette, a hard disk is rigid and fixed in place. It is sealed in a protective case to keep it free of dust and dirt. A hard[...]

Double-sided and high-density diskettes have 80 tracks on each side and double-sided, double-density diskettes have either 40 or 80 tracks on each side. Diskettes can have 8, 9, 15, or 18 sectors per track. A hard disk consists of two or more platters stacked on top of one another and thus has four or more sides. In addition, a hard disk has many m[...]

1.2MB drive-Use 5.25-inch, double-sided, high-density, 96 TPI, 1.2MB diskettes. These diskettes contain 80 tracks per side, 15 sectors per track, and hold up to 1.2MB of information (approximately 500 pages of text). 720KB drive-Use 3.5-inch, double-sided, double-density, 135 TPI, 720KB diskettes.
