People worrying about the storing capacity in their laptops, digital video cameras and other devices should stop doing so says Hitachi Ltd. Its investigators says that it has successfully brought a key component in the hard drives which will pave the way of storage devices to 4 terabytes for desktop computers and 1 terabyte on laptops in the coming 2011.
When you have a terabyte, then you have space to store 1 million books, 250 hours of high-definition video, or a quarter million songs. Whoops! Now, we can understand that we are truly moving to an advance stage increasing the storing capacity of hard disks to such an extent.
Hitachi will present effort at Perpendicular Magnetic Recording Conference in Tokyo on Monday, revisits a technology known as giant magneto-resistance.
The reason for the hard drives to increase the capacity is that the space between the data have been more chocked up and made closer and also made the heads of the hard drives more sensitive so that it can easily read the data.
The hard drive industry or the manufacturers of the hard drives not only kicked when new technology sweeps in but GMR allowed very thin layers of alternating metals to make fallible changes in magnetism - which became one of the reasons for the ever-increasing sizes of the hard drives.
But, when industry took a turn and placed with a different kind of head altogether (which might run into capacity problem, soon) then GMR is now again making hark back with a different and fast successor.
The successful making of the hard drive made Hitachi create the world’s smallest disk drive heads in the 30-nanometer to 50-nanometer range, or about 2,000 times smaller than the width of an average human hair
