    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 (3.5-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.
