"Your friend the traditional hard drive may be undergoing changes soon. No, we're not talking about the threat that flash storage poses to the dominant storage medium, though that's an emerging player on the scene. No, our favorite plattered friend may be reorienting itself in a literal sense. Perpendicular storage is coming to a computer near you, perhaps sooner than you think. What is it? We'll break it down for you as Seagate comes to market with the first fruits of a promising technology." Update: People, you just got to watch the flash animation... It's... Really, just go see it.

5.25 disks & multiple platters are very old world.
HDDs need less disks, smaller dias, less mass/inertia, to spin faster with less power so less heat. Spin speed precision & spin-down/up speeds is continuously adjusted in a digital servo loop.
Multiple platters complicates drives because their tracks & sectors must be extremely coherently aligned thru cylinders comprised by used disk surfaces. Motor bearing wear, shocks, disk clamp loosening, thermals etc can deform the coherency of tracks & sectors thru the cylinder. Miss-aligned disks, degrades head servoing which degrades data read/writes times. It only gets worse as areal densities, ie track & bit densities improve.
In each product generation, the single platter product is the sweet spot and the multiple disk products are marginal and unprofitable in commodity markets.
