I'm not so sure. Last time I followed the field, modern HDDs were nanostructured, such that each magnetic domain was literally a physically distinguishable object, in a sense. I'm not sure if that's still the case, and I'm also not 100% sure that ever made it in to production, but I'm pretty sure it did.

At least as of the last time I read the domains were a pretty uncontrolled result of the crystalization and each bit is covering a few statistically. Nanopatterning of the sort your describing would let you make the bits smaller and hence weaker by ensuring a separation and friendlier magnetic environment.
