I've long wondered who could have made those store brands. The Kmart ones I had held up a lot better than any other cheap brand I could afford as a kid. They were still quite playable when I experimented with digitizing some of them about ten years ago.
Scary thing is, some of the labels on my Laserdiscs are starting to look like the labels on that cassette. The glue is fossilizing. Already had a disc where the labels fell off after being played for the first time in years.
