Techmoan demonstrates the Tefifon, a vintage German audio player that combines elements of record and tape with a grooved elastic loop. He shows how it works and plays it.
Why Hacker News points people here: HN fans use it as the gateway to the Techmoan channel and praise it as one of the most fascinating obscure audio formats.
Coolest obscure format covered, a tape loop with grooves.

The coolest thing he's covered, I think, that I'd never heard of before is the tefifon: this video It's basically a continuous loop of tape (similar to an 8-track) but with groves recording music (like a vinyl record). It didn't see much popularity outside of Germany and then was essentially obsoleted by magnetic tape. Such a fascinating technology though. In a parallel Universe it probably would have been vastly more popular.

My gateway video was the one on the Tefifon - this video - a consumer music playback format. Production ended the same decade we stood on the moon.

“I can also recommend Techmoan.”
Techmoan reviews obscure old HiFi gear like the Tefifon.

If you want another rabbit hole to start down, I can also recommend Techmoan. He doesn't do teardowns, but instead likes to buy old HiFi gear and reviews them. Some of them are incredibly obscure such as the Tefifon: this video

“More or less ``8-track meet vinyl''.”
Tefifon is an elastic loop format, like 8-track meets vinyl.

Speaking of forgotten audio formats: Tefifon, old german analog loop of elastic, non-magnetic, tape. More or less ``8-track meet vinyl''. this videolink
