NEWS Hitachi has developed a DVD system with multiple layers, which allows far more information to be stored on a single disk - offering movie lovers the prospect of putting 200 films on just one disk. This is achieved by stacking multiple data-storing layers on a disc to allow reading and writing of a vast amount of data that can run up to 400 hours. The report said conventional DVD storage technology allows up to two layers to be used on one disk, but Hitachi's breakthrough can boost storage significantly by allowing for multiple layers, according to a report on the Agence French-Presse news agency. A Hitachi spokesman said: "We expect demand for a DVD with a bigger capacity and hope to market the product globally in the near future." The company said it hopes to commercialise the technology, which was jointly developed with its audio and video storage subsidiary Hitachi Maxwell, by 2007.
