Abstract
A 3.5 inch floppy disk is provided with a nonwoven microfiber positioned between the thin magnetic disk and the rigid shell. The liner is fixed to the inside surface of the shell, and has a disk head slot cut out corresponding to the location of the disk head opening in the shell. A specified fiber orientation in the liner's nonwoven material provides it with more tensile strength in a longitudinal direction than in a lateral direction. Cutting the disk head slot in the lateral direction reduces the fiber protrusion and loose cuttings at the edges, and thereby reduces bit errors.
