Makers of hard drives, Seagate Technology today demonstrated a new technology that allows you to place up to one trillion bits per square inch of surface plates the hard disk.
Seagate said that this technology has no record of superdense none of the other manufacturers drive.
As described in the company over the next 10 years,
Seagate will launch a 3.5-inch hard drives,
the capacity of which will be up to 60 terabytes.
By comparison, today’s most capacious drive models have a capacity
of 3 terabytes or 620 billion bits per square inch.
Seagate
said that the latest technology trends time and again prove the old
maxim: “too much hard drive does not happen.” Thus, the social
networking site Facebook now stores about 100 petabytes alone pictures and videos.
At the same time, many now refuse storage from hard drives, preferring a faster but less roomy,
SSD-drives. Seagate
said that from their point of view, even a 10-year-term storage
systems can not completely abandon the hard drives because of their
phenomenal roominess.
To place a terabit of data per square inch of surface Seagate uses magnetic recording technology,
heated ( HAMR – heat-assisted magnetic recording),
in which ultra-precise laser to literally “burn data on the substrate of an iron alloy.
HAMR technology is in development for nearly perch years but today it is still in its infancy.
Today’s commercial hard disk drives used in most cases perpendicular magnetic recording technology
(PMR – perpendicular magnetic recording),
which has some limitations.
For example, if the magnetic “grain” to place too close to each other, trying to achieve higher recording densities,
then they can begin to interfere with each other, not allowing the read head to receive the data.
With HAMR laser system raises the temperature of the plate to 650 g Kelvin (about 377 degrees Celsius), but in a very short time – about one nanosecond.
At high temperatures the effect of magnetic interference is greatly reduced,
allowing you to encode data on the disk is much denser and read them later at lower temperatures.
Seagate say they are not yet ready to announce when the first HAMR-drives will be available, but predict that the first models will have a capacity of about 10 terabytes.
