ABSTRACT:
A centering device (10) to effect registration of a magnetic disk (11) with respect to the protective envelope (12) within which the disk (11) is encased. The centering device (10) has a receiving locus (28) upon which one face wall (16) of the envelope (12) may be supported. Locating means (30) extend upwardly of the receiving locus (28) to engage at least a portion of two discrete edges (23 and 24) on the envelope (12) and thereby fix the position of the envelope (12) with respect to the receiving locus (28) of the centering device (10). Hub means (35) extend upwardly of the receiving locus (28) at a predetermined location with respect to the locating means (30). The hub means (35) is designed to engage the drive aperture (13) of the disk (11) so as to effect registration of the disk (11) within its envelope (12). One or more recesses ( 45 and 46) and legs (48) are provided to facilitate grasping of the disk assembly (19) by the operator.
