OT; old CDs and DVDs
I've been sorting out a box of old discs from twenty years ago, Windows
95 days. There were about a hundred in two CD wallets, stored in a back bedroom, unheated in winter. Ten of them I kept, and I've been examining these on this Win7 computer. Everything I've tried is readable, utterly readable and executable; and that includes CD-Rs and DVD-Rs burnt elsewhere. ¡Viva Win7! ¡Y vivant discos viejos! Ed |

Still, I guess that paper has greater longevity than laser-burnt discs. Paper, or Vellum? It's probably too soon to say for laser-burnt media. We know plenty of them that _haven't_ survived, but those are due to poor storage, manufacturing faults, poor burning, and so on; there are lots that _have_ survived so far. Even if the laser-burnt disc had the same or better longevity than various kinds of paper?, who's to say, a few thousand years (or even a few hundred years from now) anyone would have the necessary equipment in working condition that could actually do something useful with the disc made centuries before? Well, the paper (or marks in stone) we don't have the "equipment" - knowledge - to "read" a lot of it. Before the discovery of the Rosetta Stone (not just a pop group!), we weren't able to read (I think it was) two languages, even though the media survived. On the other hand, doesn't need to be a few hundred years: I doubt most early disc packs are now readable; floppies, especially pre-PC; tape backup; ZIP discs; minidiscs ... the BBC Domesday project (used laserdiscs) ... early video recordings ... Atleast with the present discoveries from long ago, it's text or something else somebody today can read and understand. It doesn't "Somebody" - maybe. Maybe one or two people in the world: maybe none. require hardware and software from the age of that writing or knowledge of such to do it. Can you think of any technology of the past that's now incomprehensible? I've listed a few above. OK, you _might_ be able to find equipment for some of them. But some of them are getting hard to find - especially the Domesday project and early videotapes. I know that people have claimed there is (like Erich von Däniken in his "Chariots of the gods". Space alien technology!). But they've all been debunked on further investigation. Things like the Egyptians knowing about pi, having used batteries; (I was wondering how having used batteries would help them know about pi, then I realised what you meant!)

I always see DVD+R at the local Wal-Mart, in spindles of 100 and sometimes smaller packages as well. They may be putting less out than they used to, but there's always some there. BTW, I completely forgot the last time I saw blank T-120 (VHS) or L-750 (Beta) tapes there. -- Mark Lloyd http://notstupid.us/ "So, how come there are no "talking snakes" nowadays? ...

I can't imagine there's much of a market for it these days. There's still some. I still use dvd-r media for the most part, but, will still make use of an actual cd-r when it's called for. For example, not everyone owns a stereo system that can read a data disc full of mp3s and decode them for playback. Some people actually still own (and see no reason to ditch unless it dies) actual audio cd only players. And, for these people, a cd-r is the perfect media. [g] I also use the writable media for making read only iso/non iso copies of various things too. I try to keep atleast 100 of each on hand at any given time. There's one place that isn't too far a drive that still stocks writable media for a fair price. I've known the owner and the people who work there for years. For the purposes of integrity, If I'm working an infected machine in a live state, I'm purposely using tools provided via a read only source. It's an old habit and probably not necessary with todays crop of malware since it's not really worm/virus like in nature, but...I still catch myself taking those precautions. Pretty obvious I don't trust the very machines I love so much isn't it?

I have literally thousands of them as I make backup copies of pretty much everything passes thru my hands. I also have a very very large library of music and videos all backed up onto optical disk that are backups basicly to the two copies I keep of most of it on portable/external separate hard disks (movies also get burned as standard playable dvd). The optical disks are kept stored in cases in a cabinet except for the most common ones used a lot, e.g. Windows install/backup disks etc. I validate every disk when burned and I have yet to have one I can't read ... yet. I exclusively use writable disks for backup. I find re-writables can't be trusted and I use them only for my hardware dvd recorder for "taping' tv. If I want to keep that I rip it using the pc. +1 on everything you wrote, except that I no longer use CDs, DVDs are cheaper. I go by brand names, like HP, Philips and Sony and very, very rarely get a coaster. []'s -- Don't be evil - Google 2004 We have a new policy - Google 2012 |
