The new discovery will allow engineers to increase the bit density of the current disk drives. Using Nanolithography dense patterns of “magnetic islands” were made on platters giving appearance of small dots spread across in a circular fashion that are required for disk drives.
“We made our ultra-small features without any conventional photolithography, with proper chemistry and surface preparations, we believe this work is extendible to even-smaller dimensions,” Tom Albrecht an HGST professional said in a press release.
HGST claims to be the first company to make the rectangular features of the Nano imprinting as small as 10 nanometers in the radial and circular paths in a disk.
“The emerging techniques of self-assembling molecules and Nano imprinting utilized at the HGST Labs will have an enormous impact on Nano scale manufacturing, enabling bit-patterned media to become a cost-effective means of increasing data densities in magnetic hard disk drives before the end of the decade,” Currie Munce, vice president of HGST Research, said in a statement.
Considering the use of nanotechnology and state of the art equipment cost would definitely be a constraint when it comes to mass adoption of such storage technology. But HGST has claimed that this process will be cost effective and will allow hard drives to store twice as much data as is possible today at reduced cost.
