Apparently there used to be an actual index hole and an optocoupler but I cracked open one floppy disk just to be *real* sure and guess what? Zero holes. So it must be doing it in some other way, and I think it's fucking up or something.

I was curious about something and thought you might know: Why did high density perpendicular hard drives not appear earlier? That was demonstrated in a commercial product in 1984, then it didn't really reappear until 2006.

Was it because it only really helps if you decrease head height over the platter, and manufacturing of smooth enough disks was a problem? The solutions that were found to that seem pretty obvious but maybe my perspective is skewed.

am unsure, would need to look up information on requirements for read head, write head, and of media stackup and when those were developed; it’s likely that there was no need to go to perpendicular recording if areal density increase could be achieved with traditional recording

SMR appears to refer to the physical positioning of the tracks only. Couldn't find any info on the actual modulation.
