Next Generation Hard Disk Invented with Optical Data Recording System

Next Generation Hard Disk Invented with Optical Data Recording System

Scientists have introduced the technology of a more efficient hard drive, consisting of a combination of photosensitive and ferromagnetic materials.

The demand for hard drives is growing rapidly asthe number of files processed by users and their volume is constantly increasing, and more advanced software is being developed. Despite the fact that modern devices for long-term data storage have a long service life and a fairly low price, they need to increase speed and capacity.

Teamphysicists from the Federal Polytechnic SchoolLausanne has developed a technology for reversible light-induced recording of magnetic bits. To do this, they used “sandwiches” from photosensitive (MAPbI3) and ferromagnetic (LSMO) materials. When light hits the perovskite coating, it transfers charged particles into the LSMO layer and reduces its magnetism.

This technology is still experimental,but scientists claim that it will become the basis for next-generation storage devices, as it allows you to create systems with more capacity and lower power consumption. Such magneto-optical hard drives do not require special operating conditions and operate at room temperature.

Previously, researchers also found that light can increase the speed of hard drives by 1000 times.
