The units where the data is stored are getting smaller and a new phase has began for this purpose. At the end of their studies, scientists announced that they managed to store data in the atom. In the article published in the journal Nature by scientists at IBM's research and development center, it is stated that a miniature magnet as small as an atom is operated like a hard disk and performs the data storage function. The rare element holmium is used in this miniature hard disk. The magnetic field was created by technically placing the atoms of this element on magnesium oxide. Then, the working method of this magnetic hard disk was reduced to the atomic level and it became possible to store data of this size. In the information provided by the research team of the subject, it is stated that it is possible to store 1 bit of data in a single atom. This invention is expressed with the analogy of a butterfly: “Imagine that the body of a butterfly is an atom. Assume that the magnetic field it creates is the wings. If the atom is not positioned in the north-south direction, it represents the stored data. "North is 1, south is 0. So the binary code in computer language can be stored." Another scientist from the same research team stated that 80,000 gigabytes of data can be stored in an area of 6 (six) square centimeters using this technology. In this case, if we make an analogy, it means that 35 million songs are stored on such a hard disk, which is the size of a matchbox. It is said that more time is needed for this successful technology to be used on smartphones. However, it has been stated that these processes can be successful in the cold of -256 degrees Celsius. In the added information, “We are currently in the exploration phase. “There is no way yet to make this technology simple.”
