In 2006, Universal Music Group introduced the first completely paper-recyclable CD case, called the "eco pack". The sleeve is printed on recycled card, and the tray is made from International Paper's PaperFoam. [33] Universal used this packaging for issues in its 20th Century Masters - The Millennium Collection series after 2006.
LaserDiscs potentially had a much longer lifespan than videocassettes. Because the discs were read optically instead of magnetically, no physical contact needed to be made between the player and the disc, except for the player's clamp that holds the disc at its center as it is spun and read.
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.
The reverse side of an optical disc usually has a printed label, sometimes made of paper but often printed or stamped onto the disc itself. Unlike the 3 1 ⁄ 2 -inch floppy disk , most optical discs do not have an integrated protective casing and are therefore susceptible to data transfer problems due to scratches, fingerprints, and other ...

Paper materials and printed media migrated to film-based microform, for example, can be accessible for centuries if created and maintained under ideal conditions, compared to mere decades of physical stability offered by magnetic tape and disk or optical formats. [7]
This Pioneer CLD-1030 unit is capable of playing both sizes of Laserdiscs, as well as Compact discs and CD Video discs. Later models added support for DVDs. Most players made after the mid-1980s were capable of also playing audio CDs. These players included a 4.7 in (12 cm) indentation in the loading tray, where the CD would be placed for play.
