The better mousetrap usually isn’t.
At least the change to CD wasn’t mandated by the government as cooling systems, televisions, toilets, and other items commonly used in the home were.
Don’t worry... Lois Learner’s email was archive on Compact Disk too.
rock carvings last almost forever.
That’s great, as long as the LP doesn’t have any scratches.
Longevity starts with the quality of the CD itself and the quality of the burn.
Almost all CDS sold retail are trash made in basements in Taiwan. Brand means nothing as the actual CD vendor changes from batch to batch depending which basement is cheapest that day.
The only really good CDs are made by Taiyo Yuden, but be sure the ones you buy are not counterfit TYs.
I just assumed all of my CD’s were top notch quality. After all, they are delivered in ‘jewel cases’ which we all know to be durable and made with a very high level of craftsmanship.
Strange - after all the ‘high tech’ it may be best, after all, simply to own books.
And how many people are there who don’t leave their CDs in the car all year ‘round?
Funny, the Rosetta stone’s been around a while. Not so much the complete collection of the Dead Sea Scrolls, though.
Many institutions have their archives stored on CDs but the discs aren't as stable as once thought. There is no average life span for a CD, says preservationist Michele Youket, "because there is no average disc."
Back many years ago, when audio CDs were new and data CDs were just coming in, the buzz was all "indefinite", as though they were eternal.
I talked with Bill Henderson, then the University of Illinois' preservation librarian on that multiple times. He did not buy it.
Deterioration of the reflective layer isn’t the only problem.
The base layer of a CD is made of polycarbonate plastic, something I had assumed would last practically forever — not so. I bought a number of Telarc music CD’s in the late 1980’s. Several of them have completely cracked while sitting in their jewel cases inside a dark record cabinet. My house is air-conditioned year-round, so there are never humidity or temperature extremes.
Meanwhile my vinyl LP’s and shellack 78’s remain good as new.
How often do you listen to the Rosetta Stone? And it's not even in Hi Fi.
If you live aboard a boat, forget CDs - the dampness is very destructive.
That and the fact that I had a CD changer I nicknamed "Old Scratchy" are the reasons I got in the habit of copying every CD I bought and only playing the copies in the car.
The only really good CDs are made by Taiyo Yuden, but be sure the ones you buy are not counterfit TYs.
Those are the main blanks I buy for writable media.
Pressed CD = almost forever...
Burned Cds..... Depends onthe dye used...
I store all my vital information on a Cardassian one time Opto-lithic Data Rod imported straight from the Top Secret Obsidian Order supply Depot on Cardassia IV.
It costs me several liters of Bio-mimemtic gel per Exo-byte, but it is worth it.
Compact discs are a godsend to people who live with cats. No more pop ..... pop ..... pop ..... pop as another cat hair gets stitched into soft vinyl grooves.
Flash has a duration of about seven years. In no way should flash be used for archival. You will start to lose some cells (bits, really) in as little as five years.
Unfortunately, Taiyo Yuden is old news. They were bought out and have been producing so-so discs since then. I have been having very good luck with Falcon media, but I am not sure I would hold them up as a standard.
You are quite correct about brands and disc sourcing. If you buy discs from a media vendor, they are generally going to know what is going on in the industry and what discs they have which are quality - both in the disc manufacturing and the dye being used. If you buy discs at Walmart, I would say they are fine for a year or so and fine to transport files but not good for archival at all.
The Revenge of Vinyl!
Vinyl is Final!
