The preservation of optical media is essential because it is a resource in libraries, and stores audio, video, and computer data. While optical discs are generally more reliable and durable than older media types, (magnetic tape, LPs and other records) environmental conditions and/or poor handling can result in lost information.
Media at risk include recorded media such as master audio recordings of symphonies and videotape recordings of the news gathered over the last 40 years. Threats to media that must be considered when archiving important record media include accidental erasure, physical loss due to disasters such as fires and floods, and media degradation.
Optical media, such as DVDs and CDs, are susceptible to the exposure of dirt, dust, and scratches from rough handling or improper storage conditions that cause deterioration. [8] Optical media should be stored in hard plastic jewel cases or other inert plastic containers and should avoid storage in plastic sleeves. [8]
Libraries and archives enact optical media preservation procedures to ensure continued usability in the computer's optical disc drive or corresponding disc player. File operations of traditional mass storage devices such as flash drives, memory cards and hard drives can be simulated using a UDF live file system.

The idea of this recovery of the sound of old records through optical scanning started in the summer of 1999 in Lugano, among the technical manager of the Swiss National Sound Archives (Fonoteca Nazionale) Stefano S. Cavaglieri (creator and holder of the intellectual property, initiator of the project), the former director of M & C Management and Communications SA Pierre Hemmer (co-creator of ...
The Variable Media Questionnaire is a free web service that allows new media curators and repositories to share the most effective strategies of preservation for different forms of new media art. It focuses particularly on creating guidelines for preserving the art once the original medium or software is not available. [13]
Various forms of optical media, mostly disk form, competed with magnetic recording through most of the 1960s and 70s, but never became widely used. It was the introduction of semiconductor lasers that provided the technology needed to make optical storage more practical in both storage density and cost terms.
