Has anyone ever seen a cassette like this before? It's a Chinese development that has a patent. An open-type audiocassette with removable reels. Only reels of their own design can be used.
It is easy to see why these never caught on. While a schoolfriends father could roll a cigarette while driving I reckon he would have had difficulty changing the reel in a cassette while driving his car For all the deficiencies of 8 track they were probably the most driver friendly format in terms of changing media.
