I was watching a recent episode of Redlettermedia's "Best of the Worst" and one of the guys on the show was wearing a t-shirt with a diagram of the internal workings of a cassette tape, I thought that was kind of cool so I drew my own diagram (inspired by that, but my own diagram) of the inside of a tape! Maybe not so technically accurate, but gets the main idea across... enjoy!
