Pioneer Corporation has succeeded in developing an optical storage solution with a capacity of 400 gigabytes. For the DivX junkies that would technicaly be capable of storing more than 500 normal length movies onto one disc. Awesome!
They use a 16 layer method to create a 16 layer read only optical disc. Per layer capacity is at 25 gigabytes which is the same as that of a Blu-Ray disc. The specifications released seems to be for industrial content publishers but Pioneer will apply the same technology to consumer recordable versions of the technology.
The technology that went into the creation of the disc came from the development work Pioneer did on it’s DVD research. The challenge was to eliminate crosstalk between adjacent layers. The resultant solutions now offer us a 16 layer optical disc that can play back high quality signals from individual layers.
The read-out system Pioneer employed uses a wide-range spherical aberration compensator and light-receiving element to achieve stability in the playback of recorded signals. It can read out weak signals at high signal to noise ratios in the optical pick-up mechanism.
The interesting fact for Blu-Ray fans is that because the optical specifications of the objective lens such as the Numerical Aperture are the same as those for existing Blu-Ray discs, it is possible to maintain compatibility between the new 16 layer optical disc and Blu-Ray discs…
The details of this project and the resultant research findings will be presented at the International Symposium on Optical Memory and Optical Data Storage 2008 held on the US island of Hawaii come 13 July.
I just hope this revelation drives down the cost of optical storage to the point where it becomes competitive with magnetic storage.
