Re: What happend to 2.88MB Floppy Disk's

said by pandora:

When I searched, burned DVD's may have a readable life of between 2-5 years depending on the products used and storage.

Maybe something new:

said by berserken, here :

I've never trusted optical media for long-term storage.

There's something new (to me, at least) that promises long life in an optical disk.

M-DISK




Overview
The M-DISC utilizes chemically stable and heat-resistant materials that are not used in any other DVD or optical disc! These materials cannot be overwritten, erased, or corrupted by natural processes. Data is stored on the M-DISC by physically altering the data layer and creating permanent voids or holes. This new method of burning data is specifically designed to make your data endure the next 1000 years.

THAT is interesting, thanks. For long term storage, any user, particularly companies, hospitals or government has to think not only about the media itself, and media storage (not too hot, not too cold, etc) but also the viability of long term devices to read media.

I store my archival discs vertically, as recommended, in the appropriate environmental conditions and my archived discs from the 90's are starting to degrade. Most of my discs from 1994, created with Kodak 'lifetime' discs, are exhibiting media read errors.

Many of my no-name discs from the late 90's and early 00's are a complete write-off (but I knew that buying them at the time).

I've had good luck with Verbatim DVD+R's standing the (limited) test of time I've been using them, since the mid 00's.

I had some circa 1995 / 1996 Microsoft pressed (not burned) CD's and was cleaning the house. Prior to tossing them, checked to see if they seemed readable. A complete test was not done as these are 1x media, but the files seemed to be there on a quick check.

I've had mixed results with some older burned DVD's, one was left out in light for a few months, and needed data recovery (it was about 6 years old). Most of the pictures stored on it were recovered, but not all. So far, that was my only bad experience with an older (6 years old) burned DVD. I do not recall the maker. At the moment I'm using Philips DVD-R.
