IRENE System
A completely separate technology has been developed by physicist Carl Haber. Installed in the Library of Congress late in 2006, the IRENE System uses a two-dimensional camera rotating around the record, which takes detailed photographs of the grooves. Software then uses the digital images to reconstruct the sound. IRENE often produces a large amount of hiss with the recording, but it is very capable of removing pops and clicks produced by scratches on the record surface. IRENE will only read lateral information (monophonic), but a three-dimensional scanner project is underway that will handle stereophonic and quadraphonic records, in addition to historical hill-and-dale recordings. Detailed descriptive posters can be downloaded from the IRENE Web site. These are not being developed for sale.

Famous quotes containing the word system:
“We recognize caste in dogs because we rank ourselves by the familiar dog system, a ladderlike social arrangement wherein one individual outranks all others, the next outranks all but the first, and so on down the hierarchy. But the cat system is more like a wheel, with a high-ranking cat at the hub and the others arranged around the rim, all reluctantly acknowledging the superiority of the despot but not necessarily measuring themselves against one another.”
—Elizabeth Marshall Thomas. “Strong and Sensitive Cats,” Atlantic Monthly (July 1994)
