Hitachi unveils 100 GB Blu-ray disc
Hitachi is first to have developed a four-layer Blu-ray disc that is compatible with the current generation of Blu-ray recorders and playback devices. According to a report published by PC Pro in the UK, the disc works with a “slightly modified” standard optical head of Blu-ray drives. The “slight” modification apparently can be achieved through a firmware update.
PC Pro said that there was no information on when the 100 GB disc will be ready for a commercial release.
