DVD RAM question

[filmyak]

I've got some old DVD RAM discs -- basically recordable DVDs in a permanent plastic casing, which predate the now standard DVD-R's -- and I no longer have a computer with a DVD RAM reader.

I once heard someone say that if you popped the case open and removed the disc, that you wouldn't be able to write to anymore but that it'd still be readable. Is this accurate? I'm just looking to transfer the info from the old discs onto some newer media.

Anyone ever try this? Is it easy to do? Does it actually work?
