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:
“The words of the Constitution ... are so unrestricted by their intrinsic meaning or by their history or by tradition or by prior decisions that they leave the individual Justice free, if indeed they do not compel him, to gather meaning not from reading the Constitution but from reading life.”
—Felix Frankfurter (1882–1965)
“To write it, it took three months; to conceive it three minutes; to collect the data in it—all my life.”
—F. Scott Fitzgerald (1896–1940)
