Abstract: A diskette holder for rigid-case data diskettes is disclosed, comprising a platform having a plurality of lateral grooves in the upper surface thereof for receiving diskettes. Associated with each groove are diskette support means comprising a front support face angled upwardly and forwardly from the area of the groove and a rear support face angled upwardly and rearwardly from the area of the groove. At least one support face of a pair associated with a groove has the undercut portion disposed from the plane of the opposing support face by a distance not less than and substantially equal to the thickness of the diskette to be held, and preferably parallel to the opposing support face. In the preferred embodiment, the diskette support means are positioned at only one end of each groove and successively alternating grooves have the support means at alternating ends of the grooves. Stop means at opposite ends of the grooves position the diskettes laterally and preventing lateral movement.
