Abstract
A carrier plate (15) has essentially circular openings (11) for receipt of smaller diameter circular magnetic memory disks (20). Each disk has a plugged aperture, a planar annular band (23) on each side for receiving magnetic media (8), an outer peripheral edge (24) and a chamfer (22) therebetween. An integral stump segment (30) and a pair of integral U-shape channel retainers (40) extend from plate opening (11) to a position overlapping disk chamfer (22) to prevent a disk resting vertically on the stump segment (30) from falling out of the plate (15). Vertical holding walls (40) extend integrally and downwardly from a rear leg of the channel to insure vertical orientation of the disk (20) and stop walls (50) extend integrally and upwardly from that rear leg to prevent overtilting of the disk during its insertion into the plate (15). Gaps (31, 32, 33) are provided between the disk peripheral edge (24) and the opening (11) over about 248.degree. allowing magnetic media to effectively coat the entire annular band surfaces (23).
