A data storage diskette incorporates a hub having a reduced diameter. A circular sheet of magnetic media is mounted about the hub. The reduced diameter imparts added flexibility to inner regions of the sheet of magnetic media between the bond point of the sheet and a point at which magnetic heads access the sheet for data read and write operations. The added flexibility enables the sheet of magnetic media to more readily be bent to align with a gap defined by the magnetic heads. The enhanced alignment enables a read/write axis of the magnetic heads to be perpendicularly aligned with the sheet of magnetic media in the inner regions, thereby maintaining signal amplitude in such regions.

Data storage diskette with modified hub

A liner for diskettes comprised of a nonwoven material which is thermally bonded in a closed cell pattern and which contains a binder material in amounts no greater than 1% by weight of fibers. This diskette liner shows debris reduction while not showing significant increase in flexural rigidity.

There is provided a composite sheet material for fabrication of storage envelopes for magnetic recording media, e.g., floppy diskettes. The material has a low debris count, and a fast rate of static decay as well as high stiffness and strength.
