Reading Data
The stored data is read through the reproduction of the same reference beam used to create the hologram. The reference beam’s light is focused on the photosensitive material, illuminating the appropriate interference pattern, the light diffracts on the interference pattern, and projects the pattern onto a detector. The detector is capable of reading the data in parallel, over one million bits at once, resulting in the fast data transfer rate. Files on the holographic drive can be accessed in less than 0.2 seconds.

Famous quotes containing the words reading and/or data:
“A baby is a full time job for three adults. Nobody tells you that when you’re pregnant, or you’d probably jump off a bridge. Nobody tells you how all-consuming it is to be a mother—how reading goes out the window and thinking too.”
—Erica Jong (20th century)
“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)
