It's a common myth that you can get less noise from bigger pixels. Smaller pixels only allow you to see more of it, as you can see higher frequency noise that you wouldn't see with the bigger pixels, but the SNR shouldn't be any worse.

But you're missing the critical issue with "double stepping". The head is reading half the width of each track, and then skipping all the way to the next track. It's not making two side-by-side reads on each track and combining the data. So if there's a small magnetic issue, it can corrupt bits that would otherwise be fine.
