Do I know anyone who can read DVD-RAM cartridges? (And yes, I already asked @foone )
Thanks to those who sent advice. I was able to easily remove the discs from the cartridges, and they are 100% readable on my linux box DVD drive.

@savetz i can't make it out from the labels - but are these type 2 or 4 by any chance? if so, the discs can be removed from the cartridges.

if it is type 1, then yeah, it'll need a cart-compatible reader

type should be indicated on the back of the box

@vga256 @savetz

I might still have a DVD-RAM reader somewhere, but I'd really have to hunt. Here's hoping it's the type you can remove...

@woozle @vga256 @savetz yeah i have a type 1 cart without a reader somewhere lol
@woozle @vga256 @savetz i also have a bunch of panasonic phase-change dual carts, but I actually have at least one (SCSI) drive for those

@savetz update: i just checked my parts closet, and unbelievably, TIL i own a DVD-RAM drive cartridge loader 😆

i have no idea if it works as I don't own DVD-RAM discs.

@savetz @foone You should be able to remove the lip on the bottom side of the cartridge and then you can slip out the disc.
@SuitedUpDev @foone will they be readable in a modern DVD-ROM reader?

@savetz @foone If you DVD drive supports DVD-RAM, then yes.

Depending on your OS, there are tools available to see which discs your specific drive supports.

If you run Linux, you can inspect /proc/sys/dev/cdrom/info to get a list of what your drive supports.

It should say something like "Can write DVD-RAM: 1"

@savetz @SuitedUpDev @foone

Not sure if they are readable in normal drives.

But there were drives that could read and write all three DVD-Standards +/- and also -RAM (without cartridge).
I had one from LG back in the days.
Propably much easier to find than Cartridge-Drives.

@robelix @savetz @foone A lot of drives support reading DVD-RAM.

Especially because it was used on a lot of DVD powered camcorders, which used the smaller 8cm disks (aka miniDVD-RAM).

If the drive is from Hitachi, Toshiba, Maxell, LG Electronics, Matsushita/Panasonic, Samsung, Lite-On or Teac, your changes are pretty high that it supports DVD-RAM.

@savetz @foone Can we see the other side - if it really conforms to the DVD RAM standard the cartridge is not necessary. It can be popped out and used in any regular DVD drive (that supports RAM, which usually is the case)
I really liked DVD RAM back in the days because it basically is a mass storage drive, usable for random reads _and_ writes like any USB memory stick.
@foone @nblr the discs are in transit right now, but I should be able to take a picture tomorrow. Thanks
@savetz @foone
I think you can just take the disc out of the cartridge and put it into a regular dvd drive which supports DVD-RAM? Surprisingly many later drives do that! I still have a DVD-RAM writer but it's P-ATA of course...
