Un article de mai 2004 concernant la longévité des médias gravés:
" Data Longevity on CD, DVD Media "

J'extrais ici les principaux conseils donnés dans cet article:
«
Do
• Handle discs by the outer edge or the center hole
• Use a non solvent-based felt-tip permanent marker to mark the label side of the disc
• Keep dirt or other foreign matter from the disc
• Store discs upright (book style) in original jewel cases that are specified for CDs and DVDs
• Return discs to their jewel cases immediately after use
• Leave discs in their spindle or jewel case to minimize the effects of environmental changes
• Remove the shrink wrap only when you are ready to record data on the disc
• Store in a cool, dry, dark environment in which the air is clean -- relative humidity should be in the range 20% - 50% (RH) and temperature should be in the range 4°C - 20°C
• Remove dirt, foreign material, fingerprints, smudges, and liquids by wiping with a clean cotton fabric in a straight line from the center of the disc toward the outer edge
• Use deionized (best), distilled or soft tap water to clean your discs. For tough problems use diluted dish detergent or rubbing alcohol. Rinse and dry thoroughly with a lint-free cloth or photo lens tissue
• Check the disc surface before recording
Do not
• Touch the surface of the disc
• Bend the disc
• Store discs horizontally for a long time (years)
• Open a recordable optical disc package if you are not ready to record
• Expose discs to extreme heat or high humidity
• Expose discs to extreme rapid temperature or humidity changes
• Expose recordable discs to prolonged sunlight or other sources of UV light
• Write or mark in the data area of the disc (area where the laser "reads")
• Clean in a circular direction around the disc. »
Beaucoup de ces conseils paraissent être de bon sens,
la seule chose un peu surprenante est peut-être:
« Do:
• Store discs upright (book style) in original jewel cases that are specified for CDs and DVDs
Do not
• Store discs horizontally for a long time (years) »
Voici en tout cas un sujet où l'on discute de la manière d'entreposer les DVD gravés pour les conserver: boîtes jewel, slim, boitiers cinéma, boites ou meubles sans boitiers mais avec des "enveloppes", . . .
