A US startup has come up with an innovative way to expand hard drive space

Employees of the American L2 project have come up with a way to increase the internal volume of a hard magnetic disk. The developers propose to artificially create a vacuum in the spaces between the magnetic plates of the drive instead of filling it with gas. According to the startup employees, the new method will simplify the process of producing discs and increase its capacity by a third.

As the developers explain, in a vacuum, magnetic plates will not corrode, which will increase the life of the drive. In addition, the production of discs does not require additional lubricants, the use of a carbon coating to protect the plates. Thanks to the new method, the production technology is greatly simplified. Providing vacuum space between the platters will allow for tighter placement of the tracks, which will ultimately increase the final storage capacity of the drive.

In addition, there are a number of other practices

World practice today has a number of solutions related to changing the volume of the internal storage. One of the approaches is to increase the number of magnetic plates in the device, which in turn leads to an increase in the size of the disk. However, this method is limited by the existing HDD size limits.

About 6 years ago, Hitachi proposed its own method of increasing the number of platters without thickening the disk, and this technology reduced the power consumption of the device.

The method consists in filling the inner sealed space of the disk with helium, which has a density seven times lower than that of air.

Such a filler reduces the resulting resistance during the movement of mechanical parts of the drive. At the same time, the physical properties of helium reduce the force of the flux acting on the disks, which makes it possible to arrange the magnetic plates more densely and to increase their number.

Another method of expanding the disk volume involves reducing the size of the magnetic grains, which leads to a denser recording on the magnetic plate.

However, this method causes additional complications. For example, small magnetic grains lose their magnetic charge faster, which results in data loss and leads to various errors.
