shutters 8 for covering the window to prevent dust and grime
from entering the window and damaging the disc. Figure 2 of
Ouwerkerk shows the cartridge in the storage mode, with the
shutters covering the window, while Figure 3 of Ouwerkerk
shows the cartridge in the operational mode, with the shutter
pulled back to expose the window and allow access to the disc.
Turning to Karakane, this reference pertains to a disc
holder for storing and carrying an information storage disc.
With reference to Figure 2 and column 3, lines 34-56,
Karakane’s disc holder 7 comprises a base member 9 and a sheet
member 10 formed of resin material. The sheet member 10 is
joined to the base member to form a pocket 11 having a
circular line along the edge of the joint, so that the edge of
a disc 13 housed in the pocket 11 is in contact along its edge
with this circular joint line. In this way, the disc 13 is
securely housed in the pocket 11. As can be seen in Figure 2,
when housed in the pocket, a major portion of the disc is
covered by the base member and the sheet member so that the
adhesion of dust or grime to the disc 13 is prevented.
