How Fast Can We Load From Tape?

Подробнее о видео

If we suddenly had a perfectly-reliable cassette tape, how fast could we possibly load data from it? This is a question I started pondering a while ago. To answer it, I had to do look into how data is stored on tape and how exactly we load it. Along the way, we'll find several limits and assumptions we have to work around on our quest for the fastest-possible loading.
