Wozniak on the origins of the hard disk

-They had strange things like, the head had to float above all these hidden cylinders. The multiple spinning cylinders were parallel to this. So, you could have 5 megabytes of data in a small space, and the head that flew over had a little forced air that kept it floating. A very different approach than what we use today, but it was the step that made it possible. This took us a long way. This was designed in the city I was born in, I, at San Jose, California, 99 Notre Dame Street. You can go down there. If you like the Old Spaghetti Factory, it's across the street almost, and you can see the little plaque that commemorates it. So, the start of hard disk was here in San Jose.
