There’s a good chance the digital photos you’ve stored on hard drives and DVDs won’t outlive you, but what if there was a disc that could last forever? M-Disc, short for Millenial Disc, is a new type of disc that doesn’t suffer from natural decay and degradation like existing disc technologies, allowing you to store data safely for somewhere between “1000 years” and “forever”.
Existing disc technologies write data using an organic dye layer that begins to experience “data rot” immediately after it’s written, causing the disc to become unreadable after a certain amount of time. The M-Disc, on the other hand, actually carves your data into “rock-like materials” that are known to last for centuries, meaning there’s no data rot. Apparently NASA uses the discs to store data. Hopefully it becomes available and affordable soon…

Here’s a fun bit of photo history: did you know that back in 1982, Kodak attempted to introduce a cartridge film format that resembled a floppy disk? Each rectangular cartridge contained a circular film disc with 15 exposures, and the disc was rotated 24 degrees after each exposure to line up the next frame.
Disc film did not prove hugely successful, mainly because the image on the negative was only 11 mm by 8 mm, leading to generally unacceptable grain and poor definition in the final prints. The film was intended to be printed with special 6-element lenses from Kodak, but many labs simply printed discs with standard 3-element lenses used for larger negative formats. The resulting prints often disappointed the consumer. [#]
Disc cameras were made until 1989, but the film remained in production until 1998. With over 8 million Disc cameras made in the first year alone, it’s no wonder there’s plenty for sale on eBay for just a few bucks.
