Storing digital photographs on CDs is a great way to preserve your memories but, if you want them last, there are some things to keep in mind. Archival CDs are more expensive, but more durable as their information layer is made of gold instead of a silver alloy. Discs should always be stored in plastic cases, away from extreme temperatures and handled only by touching their outer rim or inner hole. Also, it’s better to print labels instead of writing on the discs to prevent damaging them. With proper care and handling, your images will last 25-100 years!
