Turning up the heat - Magnetic data-storage devices are facing meltdown because they are running out of space. Heat-assisted technology could provide a solution

摘要

A DISCOVERY by researchers in France could be the key to new high-capacity data storage devices. Based around a microscopic heat source that can raise the temperature of a surface precisely without touching it, the technology could be used in terabyte storage devices. The current generation of magnetic data-storage devices such as hard drives is approaching a crisis. To increase the capacity engineers are making the storage bits much smaller, cramming more into the same space.
