Abstract
An improved spring structure for a micro floppy diskette is provided which utilizes a formed strip of relatively rigid plastic sheeting (preferably polyester) having at least two generally uniform wave crest regions with a trough therebetween which extend transversely across such strip. Micro floppy diskettes incorporating such spring structure display improved capacity to wipe surface portions of the flexible disk and have extended service lives.
