Hitachi intros 100 GB Blu-ray Disc, Compatible with Existing Drives

Hitachi Blu-ray Disc logo Hitachi has announced a new Blu-ray disc that has the capacity to store up to 100GB of data.

The four-layer Blu-ray disc utilizes a standard Blu-ray drive optical head, which has been enhanced to read and write data across the four 25GB layers.

Apparently, the existing Blu-ray drives will only need a firmware upgrade to be compatible with the latest 100GB disc. Earlier, many companies have come up with 100GB multi-layer discs. However, they used a specially developed optical head to read the disc.

The company said that they are currently working on modifying the signal quality of its quad-layer technology before releasing commercially. In addition, Hitachi is also planning to develop an eight-layer Blu-ray Disc that would be capable of holding 200GB data.
