Future of data storage 'is laser beams'
|

University of California Researchers contend that data storage could be shaken up by a possible replacement for long-time favoured technology longitudinal magnetic recording (LMR). As the amount of data being stored digitally continues to increase, there are concerns that the limits of LMR are close to being reached. Technological advances in the sector keep bringing LMR system ever nearer the maximum density at which stored data can be held without becoming unstable. But an experimental nanolaser system may provide the answer as researchers were able to line up the beams of light with magnetic fields and then tweak the nature of the discs to allow for up to a huge ten terabits of data stored per square inch of the disc. Although the cost of the procedure is prohibitive due the expensive lasers involved, it was suggested by lead researcher Sakhrat Khizroev that this technology could quickly break into the consumer and business markets – perhaps even within two years as it may be fast-tracked to help with the potential development of protein-based memory recording. Mr Khizroev told nanotechweb.org: "This experiment could have a great impact on the magnetic data storage industry and especially enable so-called heat-assisted magnetic recording (HAMR) - one of the most promising data storage technologies of the future."
