Disk Retainer and Packaging System for Optical Disk
The disk retainer of U. S. Patent 4,771,890 is modified so as to store two
optical disks, one on each side of the retainer.
The figure shows a front plan view of retainer 10. A first thin, flat optical disk
11 is held in the retainer's central cavity that is located on the front side of the
retainer. The retainer includes a first resilient spring member 13. This spring
member cooperates with the edge portion of disk 11 that is imprisoned under
retainer tab 14. An opposite edge portion of the disk is imprisoned under retainer
tabs 15 and 16. The front side of the retainer includes a recessed finger notch 17. Disk 11 can be removed from retainer 10 by first moving the disk out from
under tabs 15 and 16, as spring member 13 is flexed, and then lifting the disk
upward. Insertion of the disk into the retainer is accomplished by the reverse type
The back side of retainer 10 is very much like the front side of the retainer,
with the exception that the various mechanical features of the retainer are rotated
More specifically, a second optical disk (not shown) is similarly removably
mounted in a second cavity (not shown) that is formed on the back side of the
retainer. Tabs 114, 115 and 116 hold this second disk in its cavity. A second
spring member 113 cooperates with the edge of this second disk, and a second
finger notch 117 is provided on the back side of the retainer.
