  • What is it?: Holographic: Holographic Video Discs, or HVDs, are a disc-based storage medium that uses holographic technology to record large amounts of data on a disc no larger than a CD or DVDOlder than you’d think: Holographic storage has been around around for 40 yearsStill not ready for the market: As of April 2010, no company has manufactured a Holographic Versatile Disc despite the formation of the Holography System Development Forum that set standards for HVDs in 2007
  • -The compact disc, or CD, holds 700MB. The digital versatile disc, or DVD, holds 4.7GB single layer, and twice that in a double layer. Blu-ray, the latest high-definition video format, holds 50GB single layer, and 100GB double layer. Holographic Video Discs will initially be able to hold 300 GB of data, although they will eventually have be able to hold more than 1 Terabyte of data, which is 1024 GB.
  • The entire Lord of the Rings trilogy, which takes up 9 Blu-ray discs worth of space, will eventually be able to fit on a single holographic versatile disc.
  • In addition to storing larger amounts of data than other disc-based media, holographic versatile discs access the data much faster as well. CD: 1200 kbps/secDVD: 10.5 Mbits/secBlu-ray: 36.5 Mbits/secHVD: 1 Gbps/sec = 1024 Mbits/sec
  • Holography – holography is the act of recording patterns of light on the surface of the disc in order to create a three dimensional objectExamples: Holography is used on such things as bank cards, collector cards, and artwork
  • Storage: Whereas DVDs store information side by side, HVDs stores information in overlapping patterns. This allows data to be stored throughout the volume of the disc, as opposed to just on the surface
