Recall the days when the 'theoretical information density' of the hard drive was seen as the limiting factor for storage devices.

And then IBM came along with the GMR head and turned the world of storage literally on its head.

I wouldn't put it past them to do it again. There are plenty of companies out there pumping billions in applying technology, but very few of them beat IBM when it comes to creating new technology.

Very low on details, this method is. I'd like to know how exactly it works.
