Sony and Panasonic join forces for the development of the standard for optical disc Archival Disc Con capacidades desde e 300 GB a 1 TB, en el futuro, este est ndar est pensado para los discos pticos de uso profesional de ltima generaci n con el objetivo de expandir el negocio de almacenamiento de datos digitales a largo plazo.
Sony and Panasonic han anunciado hoy el desarrollo de la tecnolog a Archival Disc, un nuevo est ndar para los discos pticos de uso profesional de ltima generaci n, con el objetivo de expandir el negocio de almacenamiento de datos digitales a largo plazo.
Los discos pticos cuentan con excelentes propiedades de protecci n frente al entorno, tales como la resistencia al polvo y al agua, y tambi n pueden resistir cambios de temperatura y de humedad durante el almacenamiento. Tambi n permiten una compatibilidad intergeneracional entre diferentes formatos, lo que garantiza una lectura continua de los datos, incluso cuando evolucionan los formatos.
Todo esto les convierte en un soporte resistente perfecto para almacenar contenido a largo plazo. Tras reconocer que los discos pticos tendr n que albergar un mayor volumen de almacenamiento en el futuro, especialmente dado el crecimiento anticipado del mercado de archivos, Sony y Panasonic han participado en el desarrollo conjunto de un est ndar para los discos pticos de uso profesional de ltima generaci n.
Tanto Sony como Panasonic quieren lanzar sistemas con una capacidad de grabaci n de 300 GB por disco a partir de mediados de 2015. Adem s, ambas empresas quieren aprovechar sus respectivas tecnolog as para ampliar a n m s la capacidad de grabaci n a 500 GB y 1 TB por disco.
Grandes vol menes de datos
Recientemente, las capacidades de archivo han aumentado considerablemente en la industria del cine, as como en los centros de datos en la nube, donde los avances en los servicios de red han disparado el aumento del volumen de datos.
Tanto Sony como Panasonic cuentan con una excelente experiencia en el desarrollo de la tecnolog a Blu-ray Disc. Ambas empresas tienen previsto promover de forma activa este est ndar para discos pticos de gran capacidad de ltima generaci n en los entornos profesionales para ofrecer una soluci n eficaz que proteja los datos valiosos en el futuro.
En el desarrollo del Archival Disc ha jugado un papel determinante la cancelaci n de cruces, una tecnolog a de procesamiento de se al as como la Partial Response Maximum Likelihood (PRML), un desarrollo que permite el procesamiento de se ales mejorando el rendimiento de la reproducci n al permitir la interferencia entre s mbolos. De esta forma, es posible conseguir una mayor capacidad y una mayor calidad en la se al de reproducci n.
