Sony 12” WORM drive spinning up a WDM-6DL0 WORM optical disk cartridge

All credit goes to CelGenStudios for the video, I’m looking forward to the eventual release of a full YouTube video, one thing that I want to see in that video which I know obviously will just make the drive immediately eject the disc but I would like to see the disk cartridges interchanged between drives to see what happens and then to bypass all physical switches that tell the drive what type of disc it is by swapping the actual disc itself in the cartridges so the video drive thinks it has a video disc inside so it has to read it instead of electing it (which could lead to the possibility of formatting a more common cheaper CRVdisc with data formatting even if it’s going to be a lower density disc formatting to get a few more data discs) and seeing what video or audio if at all will come out of one of those data disks, presumably a lower densities CAV data disk might elicit some sort of audio/video output. All of the large format optical disk formats are really cool to me and really quite interesting, most are WORM but I still haven’t obtained any info on the rewritable 12“ Nikon disk at all, even the wayback machine hasn’t helped at all in finding even a sentence about it, I may possibly contact a few companies to see about the small chance that they send me some cool media or possibly a drive, obviously there are some companies that have gone bankrupt but may have some sort of connection with a different company when it was still in business that may have something like that, there is also that WDD-931 drive in the video available on an undisclosed website pretty damaged missing the dust door for the additional buttons but I don’t mind that if I get to have one of those despite needing lots of work to mostly restore.
