	Holographic Versatile
		The blue-green laser reads data encoded as laser interference fringes from a holographic layer near the top of the disc while the red laser is used to read servo information from a regular CD-style aluminum layer near the bottom.
		A dichroic mirror layer between the holographic data and the servo data reflects the blue-green laser while letting the red laser pass through.

	DSstar: Breaking News
		Holographic information storage breaks the density limits of conventional optical storage by recording through the full depth of the medium instead of recording on the surface only.
		Additionally, unlike optical discs, which record one data bit at a time, HVDs allow over 10 kilobits of data to be written and read in parallel with a single flash of light -- and the recording and reading processes do not require spinning media.
		HVDs and HVCs use a completely different technology from the conventional two-axis method and fully exploit the optical servo technologies associated with conventional CDs and DVDs.

		The discs will hold between 100GB and up to one terabyte of data on a standard five-inch disc (the same size as a DVD) and support a data rate of up to one gigabit per second.
		HVD reads and writes data at over 10kb with a single flash of the laser, and it can read and write in parallel, something optical discs can't do.
		Also, HVD discs don't need to spin like DVD discs, since the laser moves, rather than being held in place and having the disc spin under it.

		HVD, or Holographic Versatile Disc, is set to leave Blu-Ray and HD-DVD in the dark ages when it eventually bursts onto the storage scene.
		Standard discs store information in tiny dots on the disc surface, which are read by a laser as the disc spins.
		HVD uses a colinear system - essentially the reference and read laser beams are projected along the same axis rather than at an angle through a single objective lens.

		Holographic data storage is based on the technique of holography.
		This beam overlaps a second beam (the reference beam) at the location in the disc where the data are to be stored, and the resulting light pattern is the combination of the two beams.
		The light that reflects from the disc surface will contain the checkerboard image that was recorded at that particular location and reference beam angle.

	Holographic Versatile Disc - America's Debate
		Holographic Versatile Disc (HVD) is an advanced optical disc technology still in the research stage which would greatly increase storage over Blu-ray and HD-DVD optical disc systems.
		For example, it might be nice to have the entire library of congress on six HVD discs, but without a complete revolution in intellectual property rights, it would still cost many thousands of dollars to buy each set, putting it beyond the reach of most purchasers (except maybe funded academic libraries).
		Plus, without broadband links of comparable data transfer rates, the discs would be out of date as soon as they were printed.
