BASF Ferro Super I Audio Cassette (1989)

One of the problems with striving to improve Type I normal position audio tapes was that whatever manufacturers did with them, they were always still Type Is. That may not have been a problem technically. If the sound and signal to noise characteristics were massively better than those of a very basic, low end Type I, then a higher end Type I would have merit and, in real terms, justify its extra cost.
