Hard disk Future Technology 2015

In the future the hard drive 'settled' by 2015

Summary: hard disk drive company would plan to go ahead with the set plihan with magnetic recording (HAMR) technology-assisted heat, put the media bit-pattern on the back burner.see Also Hard drives already in-2015

Memory storage and magnetic technology expand to meet needs of the mass storage market in the future even flash-based technology eroding market higher performance. You can find out more about the development of HDD, flash memory MRAM and spin-based devices in the Storage Visions Conference conducted on January 4th and 5th, 2015, held in Las Vegas, www.storagevisions.com.

Over the years, the company hard disk argue what the road map set that will provide the industry with next gen standards for any further increases in the density of data would require a huge investment.

One group, led by Seagate, lobbied way to heat-assisted magnetic recording (HAMR); Another case made by Hitachi GST leaders, called for moving to the bit-patterned media.

EE Times reported that to find kasepakatan both sides gathered in HAMR to determine the steps berikunya

"There is a the possibility of a big shift out upright at least three years, so the mainstream [HAMR] product will not be delivered until 2014 or 2015," said Mark Geenen, President of IDEMA, trade groups and a number Diskcon disk drive, an annual event that industry will held next week in Santa Clara, CA.

Magnetic disk recording techniques today (perpendicular) will hit a brick wall in one two generations when the density reached 1-1.5 terabits per square inch. At this point, the bit is stored is too small to remain stable; a small amount of heat is all that is needed to create nano-sized bits reverse their magnetization direction.

HAMR technology using magnetic recording media are more stable at normal temperatures but must be heated before the data could be written. Challenges is a to heat a very small area fairly quickly by using materials appropriate recording can also integrate the laser diode and the recording head. While difficult, sources say it is easier than leading alternative - to form a uniform pattern of several terabits of data on the plate.

Supporting bit-pattern has not shown how it can be used to mass produce disks and add no more than two dollars to the cost of each disk.

Meanwhile, Japanese suppliers of disk drive head TDK has built HAMR head. According to reports, TDK has the potential to produce 2TB 2.5-inch disk drives with 1TB platter using this technology.

But it until all the parts were in place for HAMR, drive makers are expected to use magnetic recording shingle, a variant of perpendicular, to encourage density or slightly beyond terabit a.

The bit-pattern, this approach is not expected to hold up HAMR reached the limit, which could be 2020 or beyond when the density is measured in several terabits, notes EE Times. and Forbes

Advanced Storage Technology Consortium (ASTCS) the resources of the 13-member including Hitachi GST, Marvell, and Seagate's R & D efforts that will help make the leap beyond generation perpendicular recording.

In Diskcon, leading researchers will share technological advances HAMR.
