Digital archiving tools

I have used DDS DAT for years, currently trying out DLT and AIT2 drives (nice to have a 50GB native tape). While I have 100's of burnt CDs that are 15 years old by now, I don't think DVDr will be as good. And I still mess around with MO drives for my old gear, picked up a few more drives in the last year incase mine fail. ----- Original Message ----- From: "Shoppa, Tim" <tshoppa at wmata.com> To: <cctalk at classiccmp.org> Sent: Saturday, March 12, 2011 1:25 PM Subject: Re: Digital archiving tools As a data point: All of bitsavers fits on 27 DVD-R's. I'm told that Blu-Ray recordables store 25GB (single layer) or 50 GB (dual layer) but I'm not at the leading edge of media adoption. Only in the past year have I grudgingly admitted that DVD-R might be halfway decent for everyday use, but I still don't trust anything but Gold CD-R for longer term use. The mainframe people use cartridge-loaded WORM media which is 60 GB per cart. I think it's magneto-optical but who knows, maybe it's really closer to Blu-Ray type technology. For a while (back in the 600 Mbyte/cart era) I was a big fan of the 5.25" magneto optical carts but CD-R and DVD-R is so easy that I have a hard time going back.
