July 4th, 2008How HVDs Work
HVDs, or Holographic Versatile Discs, are a type of optical digital data storing devices bearing a striking resemblance to the construction and operation of more common optical storing devices, such as CDs, DVDs and Blu-ray, relying on read/write techniques based on the principles of holography. Similar to typical optical data storing devices, the first holographic memory systems were created several decades ago; however, they did not became as popular as CDs and DVDs mostly because of the manufacturing costs involved and the complexity of the read/write processes.
Lately, holographic memory systems have started gaining more ground in relation to more common optical storing devices, as HVDs become cheaper to manufacture. After all, HVDs have both significantly superior storage capacity and read/write speeds. Read the rest of this entry »
