Seeing it work by hand rolling the tape, we cracked open the casing and taped it up along one of the whiteboards and started testing it.
The videos that follow mostly speak for themselves, though there are a few issues that we found worth.
The one worth noting is that the tape needs to be taught, but also have enough room to pass something, such as a fingernail, below the tape as a standoff, similar to the pad inside of a cassette tape body.
Other than that, just pass the reader head back and forth along the tape, and try varying speeds to get different effects.
