encasement is the key

There's no excuse for a storage medium that can be soiled and ruined so easily by fingernails and fingerprints. For this, we can thank the consumer's demand that each new generation be able to play the last's. It's time for an optical medium that is completely encased, like the various Iomega magnetic media we so loved in the early 90s. That would make a worthy successor to the floppy disk.
