content: I am very happy with this product as it gives me assurance and peace of mind that all of my photos will last (at least) my lifetime on these discs (or so they promise). It has been difficult for me to locate any "archival" quality discs in local stores. Once I found out that other (cheaper/regular) discs may lose data over time, I freaked. I only found out about "archival quality" discs by accident on Amazon. After using them (and reading the description), I felt confident enough in these to actually "delete" several GIGS of yearly photo albums from my computer into my recycle bin AND then, permanently delete THAT from my computer! Now that's confidence! Anyone who knows me and my picture taking OBSESSION would be the first in line to buy these, if they needed them!
