Joe Jurneke has been designing the innards of magnetic devices since 1973, and now he’s here to answer our questions. He started with disk, and moved over to tape over thirty years ago, and is now retired – but consults with the tape industry from time to time. We talk in detail about how tape drives work they way they do, their reliability and more. We take down a couple of myths from the guy that was there, even correcting a misunderstanding Mr. Backup has had for many years. If the phrase “magneto crystalline anisotropy” has been used on any other podcast, we’d be surprised. This is a good one you won’t want to miss.
