CD-R Warning, if ever one were needed.

If I ever lost computer, external harddrive (in the fire safe -
meaning my whole house is likely gone) and the backup CDRs in my
office (which would mean my office is likely gone too) all at the
same time - then I think the loss of my photos is the least of my
problems, considering I have no home, no office, likely my hometown
is wiped off the map, possibly a terrorist has triggered a nuke,
and I'm probably dead anyway!

Not me! I made a backup of me on CD-R, DVD-R, AIT Tape, HD, B&W Silver Halide, BUbble Memory, 3½ floppy and a scratch pad.

I do an octal dump out to an A3 printer, then have the resulting
files etched into glass sheets. Its the only way to be sure.

Recent concerns about the short lifespan of CDs and DVDs have prompted some companies to roll out better and much more expensive discs. Memorex has announced their new Pro Gold Achival Media that should last up to 300 years for recordable CDs and up to 100 years for the DVDs. The new Memorex CD-Rs and DVD-Rs last longer because of a combination of a 24-karat gold layer, better dye and scratch-resistant coating.

The CD-R is rated for 52 times recording speed while the DVD-R will handle 8 times speed. According to Memorex, the new discs have handled ultraviolet light, humidity and heat in laboratory tests simulating rapid aging. Memorex is so confident about their discs that they are offering a lifetime warranty.

Other companies are also producing scratch-resistant discs and we recently interviewed Todd Kuchman, the inventor of the Scratch-Less Disc which uses small bumps and a hard coating to resist scratches.

Memorex, a company that become famous by selling audio cassettes, was recently purchased by consumer media maker Imation.

The new CDs and DVDs should be available in April. CD-Rs will cost $20 for a pack of five, while DVD-Rs will be priced at $25 for a 5-pack.

The MAM-A CD-Rs cost a little more than $1 when purchased in a spindle of 50.

What is so much better about the Memorex disks that make them 3-4 times more expensive?

Hi all!

This would be better news to report if anything were discussed
about DVD media that we all use, but i think it's a worthwhile
reminder nonetheless, and worth considering:

500GB per tape sounds OK, but I wouldn't want to search that serial
data stream for a particular picture. If I were you, I'd do both
optical and tape backups-- if the CD-R or DVD failed you could make
a new one from tape, but you would continue to have the
(more-or-less) random-access capability optical media provides.

Of course, there's the "Chicken Little" factor to consider, too.
Most editors want a story to grab the reader and the easiiest and
sleaziest way to do this has always been to command the reader's
attention with the threat of some dire personal loss or harm which
is always on the edge of occurring. Scare the poor subscriber and
he'll buy your stuff! We live in an age of
venally-instigated,calculated hyperbole, I'm sorry to say.

I wish I could disagree, but...check out a news magazine and it is all emphasis on the cover, and little, or no, meat in the stories. Hit AOL, or Yahoo's, or MSN's, or any on-line news site and you have trouble finding the stories to match the opening blurbs, as they back off and run the same old, same old inside. Six different words in an article lead seems to be all that is needed for a major new headline emphasizing the end of the world, the end of stick-free baking, the end of...something, or the start of something dire.

I thought by now we were supposed to be in the throes of avian flu, for instance, at least according to stories in September and October. So far, what? 50 or so cases in China?

Same deal with camera gear and companies. The four horseman ride, clipping off anything good that has happened...people don't seem to be as interested in good news, unless it is about a few entertainers, as they are in bad news over-emphasized.

Good grief, Charlie Brown! I've got about 160 gigs of data on three hard drives. Divide that by 8, and each back-up could cost as much as $100. Certainly the first one will. If those are 4.5 gig DVDs, then the cost goes up.

Still, I guess that's cheaper than the tape (looks to me like $1000 for the tape drive, minimum, and hundreds of bucks annually for tapes), and easier to search (is there anything out there harder to search than a tape?).

A hex dump would be more like it. Glass sheets... glass is hardly breakproof. Why dont you consider paper tape or even better, punch cards. These can store 80 bytes per card which means you would probably 70,000 cards per images or so...
 
Thank you for information. Backup becomes big problem, but it seems could be solved.

..because, if I remember right, it was also IBM who considered the
lifespan of magnetic tapes to be 5 years a decade ago.
Anyhow, the first CD-Rs I burnt are about 10 years old now, and
they still work fine. I test them every now and then out of
curiosity.

Me two. I have not experienced any problems with CD-R storage and have some, on budget disks, that are 7 or 8 years old and still work fine.
 
I have several burnt CDs that are 8 years old. They still work fine. At the time, they were also the cheapest recordable CDs I could find. The quality of recordable CDs must have been heavily degraded lately if they only last 2 to 5 years...

Agreed.

I use laptop (2.5") drives. They are more rugged than the large drives and the prices these days aren't too bad.

I gave up on CDs and DVDs long ago - far too unreliable, lack space, and their longevity is unproven. Besides which the discs are more likely to suffer from accidental heating than they are from stray magnetic fields, so HDD makes more sense.

Mostly, a room full of CDs will likely suffer neglect.
