Not immediately clear whether they wired up some signal-conditioning circuitry in between the sensors and the DAQ. very nice!

This way is much smarter for a variety of reasons. I had always reasoned that the resolution on floppies would be high, but 300,000 spots per disc is awesome. The system I use now does 30,000 with great difficulty and costs are high (100$ per array for materials, not labour).<br> I had actually had an idea similar to this but using 3 1/2 inch drive components and a glass disc.
