I write all my important files to an external 200 G Drive and then offsite it.
I mount an old drive in a USB enclosure
copy the files to it.
remove the drive and use the factory packaging.
and store it at someone else's house.
Offsite, cheap, fast.
Because I do every 6 months or so, usually with a drive that I'm replacing because its too small the cost is minimal. The "archival" copy is the one on my desktop, 20 years from now, that 200G of video will take up just a small fraction of the 400T drive that I use to run Microsoft's Ultimate Galaxy OS.
I don't worry about disk/filesystem formats because if my desktop is always the "master" copy, and if it fails, it could always read the last few copies I made.
For hard drives, CLV would require that the platter change rotational velocity as the head stepped to different tracks. A head can be seeked to a new track in less than 10 ms. To change the RPM of the platters would take *forever*. Heads can be produced very light, platters need mass to provide ruggedness.
If there was a desire to utilize the additional platter capacity on the outer tracks, it could be more simply done by writing more sectors on outer tracks.
But having a variable number of sectors per track (even if hidden by disk firmware) would play havoc with the OS's attempts to optimize disk layout.

Even a quick calculation of the amperage coming off of this sucker is ludicrous.
14' X 10' = 140 ft^2
140 ft^2 * 144 in^2/ft^2 = 20160 in^2
(and 120 W/in^2)
20160 in^2 * ( 120 W/in^2) = 2419200 W
(delivered at 110V)
2419200 W / 110 V = 22000 A
!! 22 thousand amps! Yow
You'll need a 1/2" X 6" Bussbar to conduct that much current.
