摘要

THE Large Hadron Collider (LHC), which wakes from a three-year shutdown next month when beam tests begin ahead of cutting edge experimental work, is still archiving its data using a distinctly old technology: magnetic tape. During its downtime, upgrades were made to the computer centres that handle the vast amounts of data produced when particles smash into each other close to the speed of light. But, despite the LHC being the most expensive scientific instrument built, the information it collects is still stored on a medium pretty much unchanged since 1952. Alberto Pace at the CERN particle physics laboratory near Geneva, Switzerland, which hosts the LHC, says that when it comes to storage "we are looking for cheap", and on that, tape trumps hard discs or flash memory. This isn't to say that CERN avoids using hard discs altogether. In fact, the Large Hadron Collider data centre contains around 90,000 of them, with a combined capacity of 487 petabytes - which is enough to store 974,000 years of MP3 music. But they are only used for short-term analysis: the content is stored in duplicate on hard discs for no more than a few months and is then deleted to make way for more information gathered at the collider.
