Recording Data
Holographic data storage contains information using an optical interference pattern within a thick, photosensitive optical material. Light from a single laser beam is divided into two separate optical patterns of dark and light pixels. By adjusting the reference beam angle, wavelength, or media position, a multitude of holograms (theoretically, several thousand) can be stored on a single volume.

Famous quotes containing the words recording and/or data:
“He shall not die, by G—, cried my uncle Toby.
MThe ACCUSING SPIRIT which flew up to heaven’s chancery with the oath, blush’d as he gave it in;—and the RECORDING ANGEL as he wrote it down, dropp’d a tear upon the word, and blotted it out for ever.”
—Laurence Sterne (1713–1768)
“This city is neither a jungle nor the moon.... In long shot: a cosmic smudge, a conglomerate of bleeding energies. Close up, it is a fairly legible printed circuit, a transistorized labyrinth of beastly tracks, a data bank for asthmatic voice-prints.”
—Susan Sontag (b. 1933)
