A Lifetime of Home Movies On One DVD?
Several years ago I inherited a box of home movies that my grandparents shot. I scurried over to Ebay and picked up an old Kodak projector that could show them. It was exciting to see images flickering on the screen that I hadn't seen for decades.
But practicality dictated that they be converted to an updated format that could be more easily viewed. Back then it was a VHS tape, and that conversion was VERY expensive!
But today the VHS tape has already lost some of it's quality, and so the next step is to get them digitized. But even then it would take many DVDs to hold the dozens of hours of footage.
Well, hope may be on the horizon: the Nature journal has just reported that researchers have developed a new optical recording method that could make it possible for new data discs to hold 300 times the storage capacity as a standard DVD.
The new "five-dimensional" recording could find it's way to the commercial market offering us 1.6 terabytes (not mega, not Giga, but Tera!) of storage space on one DVD.
