נחמד לאללה ![left]Japanese disk drive head supplier TDK says it has added a laser heater to its platter licking devices to enable heat-assisted magnetic recording. In non-boffinry speak, this will double disk drives' areal density - and therefore double capacity. All suppliers have to do is come up with the right chemical mix for the platters.
A proposed answer is to use a magnetic recording medium with very high coercivity, meaning it's more stable at normal temperatures but needs to be heated before data can be written. This is called heat-assisted magnetic recording (HAMR).
It requires a new recording medium, and read/write heads that can heat very small and precise areas of a disk platter's surface so that bits can be written reliably and in a short space time.
Japan's Asahi Shimbunreports that TDK has built HAMR heads. The report says TDK could manufacture a 2TB 2.5-inch disk drives with 1TB platters using this technology.
