I had a spindle of random cd-r media from a while back. Found in it some strange/old stuff:
This disk is the sketchiest stuff I ever came across. It was purchased by my boss as office supplies @ officemax ~ 2 years ago.

The top of the disks were all covered with a white plastic under which the "compact disk: recordable" symbol can barely be made out (inside the black box on the picture). Also, on the back side of the disk, a black ring covers the serial# or whatever the # is.
Onle 1/3 of the disks actually burned
