According to foreign media reports, storing data on tape may sound retro, but in fact, because of its high data density, tape is still widely used for archiving. Now researchers at the University of Tokyo have made tapes using a new material that allows for higher storage density and better anti-jamming capabilities, as well as a new method of writing data to tape using high-frequency millimeter waves. < / P > < p > SSD, Blu ray disc and other modern data storage technologies can write and read quickly, but their storage density is not the best, and the cost of scale-up is also high. Although tape has not been popular at the consumer level since the 1980s, its slower speed is an acceptable price to pay for higher data density in data centers and long-term archival storage. However, there is always room for improvement. In the new research, researchers in Tokyo have developed a new storage material and a new method of writing materials. The team said it should have higher storage density, longer life, lower cost, better energy efficiency and higher anti-interference ability. < / P > < p > “our new magnetic material, called epsilon iron oxide, is particularly suitable for long-term digital storage,” said Shinichi ohkoshi, lead researcher of the study. “When the data is written to it, the magnetic state representing the bit will resist the external stray magnetic field, otherwise it may interfere with the data. We say it has strong magnetic anisotropy. Of course, this feature also means that it is more difficult to write data first; however, we also have a novel way to solve this problem. ” < / P > < p > in order to write data, the team developed a new method they called focus millimeter wave assisted magnetic recording (f-mimr). The millimeter waves with frequencies between 30 and 300 GHz are aligned with the epsilon iron oxide belt, and under the influence of an external magnetic field. This causes the particles on the tape to flip their magnetic orientation, producing a bit of information. < / P > < p > “this is how we overcome the so-called” three difficulties of magnetic recording “in data science, said Marie yoshikiyo, author of the study. “The three difficult problems describe that in order to increase the storage density, you need smaller magnetic particles, but smaller particles are accompanied by greater instability, and data is easy to be lost. So we have to use more stable magnetic materials and create a whole new way to write them. To my surprise, this process can also be very energy-saving. ” < / P > < p > the team has yet to elaborate on just how dense the new technology is – instead, the study seems to be a proof of concept. This means there is still a lot of work to be done, and the team estimates that devices based on this method may be available in five to 10 years. At the same time, we may see the emergence of many different storage technologies, such as laser etched glass slides, holographic films, DNA, and the genome of living bacteria, but there are always advantages to improving existing infrastructure.
