Holographic Versatile Disc (HVD)

I was Wiki-surfing today about interesting topics and came across this. This disc uses holography to store data and is based on volume-based reading rather than surface-based reading like current media discs (3D as opposed to 2D). HVDs can apparently store 1 to 10 Terabytes of information.

I also read that potential write speeds are 1 gigabit per second and read speeds are 1 terabit per second for related media.

Quite interesting stuff! Although it says that they probably won't market them until 2019-2020. It's a considered media storage device for Ultra HD Video. Whenever that happens. Another storage media considered to be the next media standard is the SVOD.

    Sounds intriguing, and i would love to know how it worked. But i think it'll be ages until someone can explain it coherently (heck, i only learnt how DVD's/Blu-rays worked last year!)

    1 to 10 TB?

    *whistle*

    Now THAT may be able to finally max out the visible resolution of 35mm film!

    From what I understand, current media (CDs/DVDs/BDs) relies on single-layer 2-dimensional surfaces which a laser reads from/writes to. It's kind of like a a needle and a record I guess in basic terms. It senses differences on the surface. This stuff I guess you already have figured out. With 3D optical media there are actually multiple layers and multiple lasers used to read each layer. Thus the information is stored/read on a 3-dimensional plane and is based on volume rather than surface. Holographic Versatile Discs, rather than using multiple layers, instead use holograms to store information 3-dimensionally. Like those "rainbow" 3d holograms seen on credit cards and cell phone batteries and such. Underneath the holographic layer is a standard alluminum layer (the same kind used in CDs, DVDs, and BDs) which gives servoinformation (which, on a regular CD/DVD/BD, would be mixed in with the stored information on the disc).

    I'm paraphrasing stuff that's already on the Wiki entry, though.

    Incidentally, the proposed Ultra HD resolution (seemingly officially dubbed "Super Hi-Vision") that this storage media is hoping to be storage for is 7680x4320. That's huge. This image depicting the differences between current media resolutions is an interesting look at just how huge it is. It's almost ridiculously huge.

    Ah, but if you turn the HVD over, will you hear "Help us, Obi Wan! You're our only hope!"?

    Only if the restraining bolt hasn't short-circuited the recording system.

    Well, well, well, maybe I'll make my switch from dvd to hvd by then. Blue Ray just doesn't really do it for me.

    It's holographic, dude!

    Ultra HD? What are they gonna call the next thing after that? Ultra Super Extreme HD?

    Actually, Ultra HD seems to be the code name. The official name is going to be Super Hi-Vision.


    ....not much better, really.

    I think it's worse.
