Since the demise of negatives, it has been a continued challenge for photographers to reliably archive their digital files. Delkin has carefully developed a solution for those looking to preserve their images beyond the course of their career. Archival Gold offers the most unique and trustworthy CD-R, DVD-R and BD-R discs to safely store your most treasured digital data. This is the only storage medium guaranteed 100% uneditable, inerasable and tested to endure up to 200 years based on the National Institute of Standards and Technology. Users can conveniently refer back to their original data files & images when necessary and even pass them along to future generations. Each Archival Gold BD-R holds 25GB (about 5 times the largest DVD-R and 33 times the largest CD-R capacity) and boasts superior 6X speed. This equates to roughly 2 hours of full high definition playback and 23 hours of standard video.
