Chinese researchers discover new method to store 1,024,000 GB in a single DVD


Most of us have probably moved on to using Blu-rays now, but the old DVD might have just received a big shot in the arm. And I mean big.

A bunch of Chinese researchers have discovered a new method that could theoretically allow a single DVD to store 1,000 terabytes (1,024,000 GB) of data. That’s a whole petabyte of storage in a medium that when it was first introduced was only capable of 4.7GB.


The DVD format was limited by the size of the laser, which Blu-ray eventually surpassed by using even smaller lasers — but that too hit a limit. According to Gizmodo‘s conveniently simplified rundown of the process, the researchers have developed a new method that uses two lasers that can cancel each other out, effectively creating smaller pits on the disk and increasing the amount of capacity.

But before you toss out the Blu-rays, note that it might be some time before this technology will reach the consumer level. While the data can be created, they still need to figure out a way to actually read it. Also, burning a 1,000TB disc sounds like it could take awhile.

    [@David Roper] Actually, I don’t. Even though I had access to two IBM 360’s in high school, I used them only to program output of smiley faces. A friend dragged me kicking and screaming into the world of computing twenty years later to help with his systems-integration business. I never touched a floppy (or anything else related) until 2001. I even managed to resist recruitment by an early girlfriend’s father who was a civilian employee for the US Navy working on what we now call the Internet. I’m a no0b.

    I agree, however, that those WERE the good old days when everyone knew, “Real Men Don’t Eat Quiche”.

    Do you remember the alignment probs we used to have with 360 vs 1.2 Meg floppy disketes? Man oh man, talk about alignment problems. I had to go back and find the same drive the floppy was written on where I worked. The 1.44s were stable at least. Ah, the good old days when men were men and women were women. “Those were the daysss” (Edith singing)

    [@David Roper] Will do. Betamax: Remember the visceral arguments vis-à-vis VHS ?

    Re: This super-duper DVD – The read-drive will have to be extremely precise and stable, probably like the heads on today’s HDDs.

    @Joleca – Do you pay that Kitty prevailing programmer’s wages? :-)

    [@JMJ] JMJ, and I recall my purchasing from a drug store, a wire recorder for $30. It was a small size using a 3 inch reel of wire that actually worked like a tape recorder. Battery operated okay, but Wire? What was I thinking. I’ll bet eBay folks would like it now. Huh?

    Imagine how many videos and backup data files you can lose when it fails or gets lost in your house? Reminds me of the Tandy CC when I started putting programs – each one – on a single 20 minute cassette so I would not lose many on a single 60 min cassette.
    Man, that takes me back. Thanks.
