Engineer Guy vs The Computer Hard Drive

Bill’s back! And his subject this week may be the ultimate example of a truly astounding piece of engineering that we all tend to take for granted: The computer hard drive. A favorite college physics professor once admitted to me that the hard disk drive impressed him more than almost any other single piece of modern technology, and I have since found that, the more I think about it, the more I agree with him. As always, Bill Hammack does a great job of explaining things in a way that will appeal to both experts and amateurs. [Thanks, Bill!]

  1. Absolutely delightful!  Mr Hammack does a wonderful job, (particularly with the animation).  I had no idea that both positive and negative spikes were “1”s.  Surprising that they never considered using trinary for even more data density.

    I hope you’re getting your cut of all the vast profits from the “cooking for geeks” sales, Bill [wink]
