I must have a couple of hundred as well
I switched to a different type of cassette for audio recording once i realised i'd be daft not to - Hifi VHS video recorder. I must have a couple of hundred video cassttes with about 6 hours of music on each one

I used that constantly until i bought a CD recorder unless what i was going to record was longer than 80 minutes.
I really have no idea why other people didn't think of using a video, after all it has an amazing signal to noise ratio (up there with CD) as well as sub 20Hz to over 20KHz response with zero need for noise reduction

It's similar to a reel to reel operating at 2M per second
