Del soporte papel perforado y cinta magnética... al disco 3d holográfico anatómico-nanotecnológico: nuevos soportes magneto-ópticos y ópticos de almacenamiento masivo de información

摘要

In this article describes itself, in the first place the evolution that the magnetic technological formats, magneto-optical and optical have experimented throughout history since the birth of first very rudimentary paper tapes perforated and magnetic in the process of reading and writing of information, until the development of the holographic technological 3D anatomical format; optical format of massive recording of information outstanding and very full of novelties, and secondly are enumerated and are explained the possible applications, of the new digital technologies of capture of characters written (OCR), and the new formats optical and new magnetic optical formats, contribute in the conservation, preservation and diffusion of the bibliographical patrimony and documentary spanish in century XXI.
