CDs and DVDs: Tons of good info

The Care and Handling of CDs and DVDs, A guide for librarians and archivists. Found while researching the layer-cake sandwich of materials in an optical disk. Disk structure page. Did you know that the top side of a CD-R is thin and fragile? I mighta mentioned it before, but this underscores it, in a big way.

Also of note: the tests for aging and shelf-life of CDs and DVDs that you can burn yourself is that their pre-writing shelf life is limited to some 5 years or so. By all means, stock up, but don’t stock up too much.

Gold disks are the best. But that’s a topic for another post.
