New technology helps increase your hard drive capacity 10 times

With a growing amount of multimedia content, 1 TB drives now also become cramped, but a new technology can increase 10 times the storage capacity without changing the hard disk size.

If you always lack memory to store images, videos and music on your laptop, then science can give you the answer. Using lasers to write data to magnetic drives, researchers can increase the hard drive's storage capacity by about 10 times. This process is also known as magnetic disc burning with heat support .

Our computer reads, writes and stores information by controlling and detecting tiny areas on the magnetized hard disk. This magnetic state corresponds to either " 1 " or " 0 " in binary code - also known as 1 bit - and our files are stored in thousands (or millions) these bits at the same time. So if we want more storage space, we need to find a way to narrow those magnetic regions - made up of magnetic particles. And that is exactly what this new development steps into.

Magnetic disc burning supports heat to increase the hard disk storage capacity by about 10 times.

As Gizmodo has reported, this new technique is based on the size reduction of magnetic particles used to store data, while minimizing the interference of surrounding particles. Researchers have now done this more effectively than ever by using an accurate laser beam next to a magnetic field.

But what does that mean? To better understand this process, you need to understand a bit about the limitations of today's magnetic storage drives, due to the need to balance the elements: readability, writing and stability. Previous manufacturers have reached the limit when making magnetic particles smaller and smaller, because the surrounding particles will create their own magnetic field to pull other particles and thus destroy the file stored on CD driver.

It has been found that magnetic materials are better resistant to these forces, but it also makes the drive more difficult to write and requires a larger magnetic field to store data, Finally, it will cause more interference to the surrounding particles. That's where this new laser technique works. It allows for more accurate recording (recorded data particles are only a few nanometers long), with a lower magnetic field due to the previous heating up of magnetic particles.

The right half is a disc that is recorded with the new technology, with much narrower dimensions than traditional recording technology.

This new approach has appeared in recent times, but scientists are still studying to find its limitations. A group of researchers from Technical University TU Wien in Austria, was able to use this technique to save 13.23 Terabit data per square inch of computer drives. This new storage disc also offers higher capacity than Blu-ray discs (about 12.5 Gigabit per square inch) or the best hard disk drives on the market (1.34 Terabit per square inch).

" We have developed a realistic simulation model for both the complex HAMR process, allowing to accurately calculate the dynamics of a device in a reasonable simulation time ." Co-author Christoph Vogler told Phys.org. " Therefore, we can systematically optimize the key parameters of the recording process to show that a HAMR device with 10 Tb / inch2 storage capacity and more is entirely possible. Such examination and density can be achieved. "

Unfortunately, writing data in the lab's simulation model is not the same as placing it in a laptop on your desk. The research team said it would take a few years before the technology became stable enough for use in consumer electronics devices. So during that time, you may have to buy an external hard drive for your photos.
