"Úgyhogy itt lenen az ideje a digitális adatok hasonló élettartamú tárolására ésszerű költségekkel."
Manapsag a legolcsobb biztos megoldas az, ha valaki kinyomtatja jo minosegu, nem lebomlo papirra, jo minosegu, nem lebomlo festekkel. Ezutan az egeszet el lehet rakni egy biztos helyre, ahol legmentesen tarolhato. Valamivel nagyobb adatsuruseg erheto el a femlemezes mikrolyukkartyak hasznalataval, ahol egy lezer rozsdamentes femfeluletbe gravirozza az adatokat (lehetoleg valamilyen egyszeru formatumban). Ezeket a femlapokat el lehet tenni nagyon hosszu idore. Hasonlo a nem tul elterjedt HDROM technologia is (nem a hddvd), ahol tobb gigabytenyi adatot kepes tarolni egy ionsugarral irt femlemez. Jelenleg csak az usa kormanya es a nasa archival ra par dolgot, pedig a technologia lassan mar tobb evtizedes.
A hdrom technologiarol mar jo 20 eve nem talalni uj infot:
"Once development work has turned into product, the upcoming HD-ROM technology seems pretty interesting. HDROM is a high-density write-once format that makes use of ion etching equipment to write data onto steel or iridium plates. With suitable error correction conventions, it should be more robust than the stone tablets of antiquity. Steel "tablets" remain readable thru "intense" treatment such as attempted erasure using mechanical devices such as jackhammers; iridium is likely to remain readable even through more extreme events such as nearby nuclear bursts. The cost of the readers does not forceably need to be much higher than that of a CD-ROM, as it uses similar laser reader technology (at a much higher density); the cost of HDROM writers (once made in quantity) is expected to start at about $10,000 for a "steel" version."
