BluRay discs offer several advantages over backup tapes for the purposes of archiving. The capacity, storage requirements, life expectancy, and cost all influence one’s decision to use BluRay discs for their data storage needs.

The hardware for tape backups can be hundreds or thousands of dollars, while a BluRay drive and recording software can be purchased for less than one hundred dollars. Individual backup tape costs vary widely. Tapes with capacity similar to single layer BluRay, such as the 20/40GB DDS-4, start around ten dollars each, while 25GB BluRay discs start at less than a dollar.

Direct thermal printers use a thermal ribbon to make the print adhere to the surface of the disc. You can use an un-coated, silver lacquer disc, or discs with specialty coatings to print to. You can even print to discs that have been silk screened with other artwork, just adding some type like a title as necessary. These printers are fast, with print times as short as five seconds, and costs of less than $0.04 per disc. They are reliable, built to run all day for thousands of discs, and can be found in many high-volume production environments. Read More
