Optical recording technology has a major advantage over other recording technologies, namely, that reading and writing of data is accomplished by light, so that no physical contact between the media and the optical head occurs. The storage capacity of these optical media (e.g., disks) is limited by the size of the smallest marks on their surfaces that can be read by the wavelength of light used. In this communication, we present a possible data storage system with molecular-sized (about 200 A°) marks that also give, in principle, the possibility to record information depthwise, rather than just on the material surface.

Abstract
Optical recording technology has a major advantage over other recording technologies, namely, that reading and writing of data is accomplished by light, so that no physical contact between the media and the optical head occurs. The storage capacity of these optical media (e.g., disks) is limited by the size of the smallest marks on their surfaces that can be read by the wavelength of light used. In this communication, we present a possible data storage system with molecular-sized (about 200 A°) marks that also give, in principle, the possibility to record information depthwise, rather than just on the material surface.File in questo prodotto:
