Scientists of Radbout University Nijmegen made a true marvelous invention. Usually, need a magnet to change the magnetic polarity of a metal. That’s how modern hard discs work. But scientists thought of a way to change polarity with laser impulses. Each laser impulse makes the information layer on the disk surface to change its value, from 0 to 1 and vice versa. This invention increased speed of hard disc in about hundred times
