yep can remember that as a thing in the mid 80s but by the very late 80s voice coil based drives were becoming the standard.
I started in IT in 89 and was doing setup work for NEC systems going into schools and some of them had 42MB 3.5" voice coil drives.
5.25" 20MB and 40Mb drives still had to be parked.
MFM drives like the Seagate ST-225 did need a park command to park the heads, more modern stepper drives and early voicecoil drives already had autopark.
Ahh, so it was just a matter of technological progression
Still find the terminology amusing. It's almost like they borrowed it from cars.
So, kind of like a record player? That kind of reminds me of Phllipps' effort in creating the CED, the effort of trying to use record player mentality with a video disc. I find failed technology can be fascinating as it can inform us just as much as successful technology.
Even less precise than a record player, if you low level format a ST-225 at low temperatures and you use it at about the same temperatures the thing will be correct that X amount of steps is where it can find the data, however, if you have a hot day and you use the drive then it is possible for the disk to expand enough that that same amount of steps isn't the right amount and the heads won't be on the track which means it can't read any data, the grooves in a record literally guide the needle, there's nothing that guides the stepper motors, there's a fixed table with each track entered into it, it can't take in account expansion of the disk or any other situation where the tracks aren't there where the table says they are located.
That's why they invented the voice coil drives, old ones use a seperate disl containing the location data, a seperate head reads it so when the drive gets hot all disks including the one with the location data will expand so that the table written onto that disk will still be correct, later on they used other methods to make sure the drive doesn't lose track of its tracks.

also meant no more little slips of paper attached the drive with information like heads/cylinders/sector and the bad track listing which was need when when setting up the drive.
autodetection of drive configuration made things so much easier though it it didn't always detect correctly in the early days.
Was watching the latest video on Adrian's digital basement today and he was working on a 386SX board and it was blast from the past when he had the bios up on the screen. Can remember the very old style bios but been so many years since I've seen one.
Bios update Grrrrrrr not happy
it reset my TPM now windows can't reactivate as it was activated via a digital license linked to my MS account. Not happy Jan
Tried all the troubleshooters and yeah will wait till tomorrow.

I found a USB with my installation files am going to try an in place reinstall.
Video I watched which might make some of you sad, a somewhat destructive server teardown

In the early 2000s we really wished computers would be pocket sized, net accessible everywhere, maybe have Trek level tech, updated color screened Palm pilots etc.
We have all those now and nobody cares about how wonderful current tech is.

Except in Star Trek that handheld computer or desktop that they have in your cabin is probably 10x more powerful than a desktop machine of today and both could run rings around machines we have now and run on power sources that last almost forever

can you imagine the now high tech era back in the 2000s era
which probley did happen on some alternate earths in the mutliverse
and why i said that well who knows maybe there are some alternate earths where high tech from the 2010s era and 2020s alrighty happened in the 2000s era
Or it jumped decades and started in the 80s... What if the internet age had started there on some Earths?
Probably yes, with our current tech though I wonder what humanity will see in the upcoming 50-100-150-200 years.
We'd have brocolli hair cuts and rizz up the girls
anything is possible in the mutliverse if you think about it
like what if 2020s era tech started in the 80s or what if the 2020s was still 90s tech
We'd have brocolli hair cuts and rizz up the girls
lol lol
