OPTODISCR004 has gone bad in a year
PRODISC R03 had failed within the year
So far only one TYG02 has shown to be bad
OPTODISC,OR was recorded 8 months and now is unreadable.
I can't believe all these backups are ruined.
I just went through 125 DVD-R backups and I have over 20 that have failed and are unreadable.
I've tried them in a different computer & drive & the same errors are there.
All these were stored in individual Zip Lock Baggies and kept in a box away from light.
I'm really concerned and don't know what to get for long term.
The TYG02 have a good following here, I'm going to get several hundred and back up my backups while they're still readable.
Losing so many in such a short time is not comforting
wilhelm a écrit:In order to have a disc that lasts a long time, there are several critical criteria that must be met:
1) a good quality recording.
This is dependent on the compatibility of the drive and medium and on the quality of both. Mentioning MID codes is insufficient information if the code is not included in the drive's firmware memory.
2) a stable dye, reflector, and bonding agent.
Although some have dissed Prodisc's media or Fuji media,
they use Fuji's Oxonol dye.
There is a growing body of evidence to suggest this dye is more environmentally stable than azo-cyanine dyes.
Gold is not a good reflector for DVDs. It is fine for CD-Rs, but the reflectivity is lacking as far as DVD specs go.
3) proper storage.
This includes handling as well as absence of light and heat/humidity. Humidity is particularly harmful for DVDs because of the sandwich construction.
Environmental tests suggest that a well recorded DVD will last 40 years before the increase in errors overcomes error correction capabilities. CD-Rs will last 120 years under the identical conditions.

Ce dépend de la compatibilité de la commande et du milieu et de la qualité de tous les deux. La mention de MI codes est l'information insuffisante si le code n'est pas inclus dans la mémoire des progiciels d'entraînement.
2) un colorant, un réflecteur, et un agent stables de liaison.
Bien que certains aient dissed les médias de Prodisc ou les médias de Fuji,
ils emploient le colorant d'Oxonol de Fuji.
Il y a un corps croissant de l'évidence à suggérer que ce colorant soit plus ambiant écurie que les colorants azo-cyanine.
L'or n'est pas un bon réflecteur pour DVDs. Il est très bien pour le Cd-Rs, mais la réflectivité manque dans la mesure où Spéc. de DVD disparaissent.
) stockage 3 approprié.
Ceci inclut la manipulation aussi bien que l'absence de la lumière et de la chaleur/d'humidité. L'humidité est particulièrement nocive pour DVDs en raison de la construction stratifiée.
Les essais environnementaux suggèrent qu'un DVD bien enregistré dure 40 ans avant que l'augmentation des erreurs surmonte des possibilités de correction d'erreurs. Le Cd-Rs durera 120 ans dans les conditions identiques.

En s'y mettant à plusieurs, on doit pouvoir en avoir plein d'autres
Donc, si je comprends bien, les Riteck de Fuji sont meilleurs que les Tayo Yuden et les Verbatim de fabrication Mitsubishi Chemical...
... les Riteck de Fuji sont meilleurs que les Tayo Yuden et les Verbatim dont le colorant est de fabrication Mitsubishi Chemical...

Assuming that :
1. The burns are good (good burner, reasonable burning speed like @12X max for @16X rated media)
2. The discs are in good condition before the burn (no excessive dust, no scratches, no defects)
3. The discs are stored in good conditions (humidity <65%, temp < 30°C, no daylight, no horizontal storage, no free standing in paper or plastic sleeves, no paper labels)
4. The disc are handled carefully
5. The batch of blanks is not a problematic one
6. The discs are genuine (no fake mediacode)
... the following MIDS are then fully reliable *in terms of stability*
according to my personal experience and what I gather on this board and others:
TDK TTG02 (out of market) /
MCC02 RG20 (disappearing) /
MCC03 RG20 / MCC 003 (disappearing) /
MCC 004 /
YUDEN000T02 (disappearing) /

Then, you have to understand that except for some proven unstable MIDs like Ritek G04 and G05,
the 6 points above are MORE important, in terms of longevity, than the disc model used
