I bought a stereo system in the '90s and it's still my main stereo that I use today. It has a mini disc player built in. At the time I bought it it was the cutting edge of technology. I never bought any albums on minidisc, but I did buy some blank ones to fill up with music, and I still have those. Compared to tapes, the sound quality of minidiscs was/is really good. Also they're a lot more durable than CDs.
Apparently Japan still manufactures minidisc players.
