Method of merging two disks concentrically without gap between disks

摘要

A disk cassette is provided with opposed side walls having ribs configured to facilitate merging pairs of disks. In most instances, the disks will be single-sided hard memory disks. The final position of the disks in the disk cassette will be in spaced pairs, with the disks forming each pair being in surface-to-surface contact and, preferably, with the perimeter edge of each disk concentrically aligned.
