Sony en Nippon Zeon hebben een harddisk in ontwikkeling die is opgebouwd uit plastic schijven. De produktiekosten van dit grapje zouden 30 tot 40% lager zijn dan die van traditionele aluminium schijven. Onderstaande info komt van The Register:
Sony would not confirm the figure, but acknowledged that they would be less expensive to make. A spokesman said that this was because they did not need the same polishing process. He would not comment on a start date for commercial production.
Analysts were not impressed, however, saying that it was not yet clear which of Sony's many proposed technologies would be best. The company is also discussing plastic disks with US based Castlewood Systems, and new aluminium and glass disks with Quantum and Western Digital.
