Yeah, knowing how science and tech journalists often have little idea what they are talking about and the description itself, I'm skeptical that this will be as revolutionary as it's being presented to be. I'd love to be wrong, though.
And it does sound like extra speed is possible. It sounded like the magnetic platters in hard drives are too magnetic, and spend some time compensating for undesired electromagnetic effects that occur while reading the platter. Which makes sense because it's spinning fast while another electromagnet tries to read it and electromagnetic fields moving relative to each other are known to react and interact. Part of that would be how it works at all, but there could be another part that counteracts that and maybe requires time to stabilize or multiple passes to give an accurate average.
Though this is pure speculation, I don't have much in depth knowledge of how magnetic drives work, other than it involving neat tricks like spinning, magnets, and probably some sort of sorcery or witchcraft.
