durability
editI have very big doubts about optical media being more durable than tape and specially than LPs. I have LPs which are 100 years old and still play reasonably well. Meanwhile,many cd-rs burned less than 10 years ago aren't even recognized anymore.
- The durability aspects come more from handling than static storage issues (assuming vaguely proper storage technique is used). The automobile dash is not the place to store anything (but the sticky note grocery list LOL). And, as any experienced older audiophile can tell you, each and every time you play an LP you deform it ever so slightly thus changing minutely its playback characteristics. Sadly, the laws of physics must be obeyed (though fortunately proper setups can minimize the damage). LOL Tape was a great idea and cassettes made music a thing for the masses. The reason "many cd-rs" (and dvds for that matter) fail as described is due to the cost constraints of mass production coupled with general carelessness (hence the storage advice above). Proper materials and manufacturing techniques can, and do, produce what is generally called "archival grade" optical media. Making copies of the wedding for out-of-towners? Feel free to use any old discs from local retailers. However, the original of that wedding video should be on an "archival grade" disc (or a USB memory stick?). That's my 2¢.

Blu-ray
editCould some reliable information on Blu-ray durability and preservation be added, including effects of sunlight? Martin852 (talk) 01:25, 23 September 2011 (UTC)
- Here, here! I don't have any Blu-Ray equipment yet but it seems like the vastly expanding size of data needing to be archived in small quantities (like Aunt Matilda's last interview) need the kind of storage space provided therein. JimScott (talk) 15:26, 6 November 2014 (UTC)
importance scale rating
editI'm not really involved in these rating schemes but it seems like computer information backup is an incredibly important topic. Most people ignore it until something irreplaceable or valuable is lost. Why is that? IMHO, it is because the technelite have failed to provide a simple, reliable means to archive information at a consumer-level cost. I was reading through NAS comments on Amazon this morning and was amazed by the comparative complexity required. It isn't a technology limitation. All the technology exists (RAID 1, wi-fi, ethernet, etc., etc.). But no one has put together a box that one can just plug in to the wall outlet and the home network, and start using. For now I'm using USB sticks but with terabyte drives, that "solution" is getting unwieldy. Market opportunity? Yes. Important? IMHO, even more so. JimScott (talk) 15:36, 6 November 2014 (UTC)
- Good point about market opportunity for larger drives. As a person who trusts ROM storage more then RAM, I'm actually wondering what ever happened to the Five-D or 5-D disc? Apparently these things were prototyped at Melbourne Swinburne University in 2005, it was developed further in 2009, and around 2011 Samsung bought out the rights or the technology of the medium. I believe these discs were able to hold up to a Terabyte of info, for me anyway, an absolute blessing when storing my large lossless music collection, which I currently have across four external hard-drives, and hundreds of DVD-Rs for double back up. To me it's the best and safest backup method at the moment, but the amount of DVDs and External hard-drives is also getting rather unwieldy.
My question is though that there is another new archival medium of optical media missing from the list. I've been searching all morning on Google and Bing, but can't find anything, a friend sent me a link about this disc medium three months ago, but unfortunately I've lost my surfing history. All I can remember was that the discs were gray in colour and made of a newly developed material. I don't know if Verbatim had anything to do with it, but hope I've striked a mental note with someone. :( :(. Whitewater111 (talk) 00:46, 5 July 2015 (UTC)
Nonsense
editThe storage section is nonsense. It doesn't matter if discs are stored horizontally. The cases are designs so that the surface of the disc floats above the case. It doesn't touch it. Also, the part about removing any paper inserts is beyond nonsensical. The minuscule amount of moisture that may collect because of it is NOT doing to hurt the disc. — Preceding unsigned comment added by 67.241.240.42 (talk) 15:00, 22 April 2024 (UTC)
