Magnetic Recording Assisted by Heat Promises to Achieve Record Storage Densities
Hard drives soon will be able to hold up to 1 Tb of data per sq. inch. Storage maker Seagate has introduced new magnetic recording technology called Heat-Assisted Recording which will allow manufacturer to increase disk capacities upto 10 Tb and higher; 1 Tb (terabit) equals 1000 Gigabits. Heat-Assisted Magnetic Recording (HAMR) approach is going to double the storage density of today #39;s best hard drives and it looks like Seagate will be the first storage maker to reach and cross the 1 terabit per square inch benchmark.The same technology promises to deliver extraordinary capacities of upto 60 Tb within next ten years with theoretical storage densities reaching 10 Tb per sq. inch - long way from today #39;s 750 GB per square inch area density. That, and the new generation of data compression algorithms could bring us to the next level of capacities we never dreamed of. The rise of Internet, online search and cloud computing continues to demand for greater storage capacities in our data-hungry age. One of Seagate executives Mark Re admits that advances in magnetic recording fields such as HAMR will become strong influences in upcoming future able to support ever increasing demand for more space. There are only few known ways to increase areal density - by packing more bits of data per linear inch of track and by placing tracks closer to each other. Hard drive manufacturers have been able to double disk capacities almost every couple years. Today, Seagate has achieved the linear ...From:technotomorrowViews:0 0ratingsTime:01:45More inScience Technology
