Sony has developed a new 128GB HD DVD, capable of storing up to 4 hours of HD video recording.
The new disc format will be added to Sony's XDCAM Professional Disc line, which already features a dual-layer 50GB disc and a single-layer 23GB disc.
Sony has enhanced its XDCAM line with better storage capacity and improved writing speeds.
Kazutaka Hasegawa, the general manager for Sony's media division, said in a statement to tech news site The Inquirer: “This new disc's unique combination of large recording capacity and high transfer rate opens a new frontier for this proven professional optical disc format in the area of video file archiving applications.”
The new disc, which is also known as PFD128QLW, has been designed using Sony's blue-laser technologies and high density recording technique, allowing it to offer more storage at higher speeds.
Sony explained that the write-once feature on the disc made it perfect for long term archiving data as it prevents tampering and unintended erasure.
