    The firm developed the cutting-edge technology with Hitachi Maxell Ltd., a subsidiary specialising in audio and video tapes.


    "We expect demand for a DVD with a bigger capacity and hope to market the product globally in the near future," said Hitachi Ltd. spokesman Takeshi Kawakami.


    The latest technology involves stacking multiple data-storing layers to ensure accurate reading and writing of a vast amount of data that can run up to 400 hours.


    Expanding DVD storage capacity requires increasing the number of layers used in a DVD. Conventional technologies so far allow up to two layers in a DVD while Hitachi's technology allows multiple layers.
