There was a time when Bill Gates of Microsoft had said that an individual in his life time would not need more than a few MB’s of memory and today we have people not only buying TB’s of memory but exhausting them as well.
Hence it only makes more sense for disk space technology to develop more and increase the capacity. But the one we have just heard was totally unprecedented.
Seagate has come up with a disk drive which comes with a density of one terabit per square inch. If that didn’t sound impressive here is another bit of fact that might draw a few O’s. The hard disk contains more bits in a single square inch than the stars in the Milky Way, which have around 200 billion to 400 billion stars as estimated by astronomers.
Seagate was able to achieve this with the help of heat-assisted magnetic recording (HAMR), which allowed them to seriously hammer some breath taking amount of memory in such a small space. The current hard drives use perpendicular magnetic recording (PMR).
Sadly the technology will make its debut commercially only later in the decade, helping double the current storage capacity on hard drives.
