Many of the Naks actually remove the felt pad altogether to improve audio quality. Tape is held against the heads with backtention, like pro reel to reel decks.
Love the sound.

In some cassettes, the glue may fail, causing the pad to wander off-center or fall out entirely. In a case like that, put the tape in a new shell, because the misplacement or absence of the pressure pad will cause the tape to mistrack.

>> An interesting machine would be a cassette mechanism up top but instead of a capstan drive, the tape would be pulled out the middle of the shell and put in a little isolated-loop drive, Technics style, with the heads inside the loop. I would think, if you had really good guidance on top of the loop, you could keep the tape very stable in the loop. Better still would be a way to adjust the two pinchrollers so you could vary the tension/wrap on the heads. Cassette tape is so thin, that should be a way to guarantee good head contact.
