By way of the Japanese website Burnup.cx we can find that Ricoh has a special website that announces the development of a technology that should be able to store more then 100x the amount of data that can currently be held on a DVD disc. Also Ricoh is working with a technology that is called three dimensional multilayer and this should make the large quantities of data storage possible.
Also other companies have announced in the past to be working on these kind of technologies, but Ricoh is for now the first to announce a date when it becomes available to consumers. Below some addition information badly translated with Babelfish from Japanese:
Don't you think? the " record mark ", whether " 0 " or " 1 " in order to distinguish the digital signal which is said, just there is the part where reflectance of light was changed. |
The so is. In order to make the small record mark, it is necessary to make optical spot small, but focal length of the lens became short because of that, because distance of the lens and the disk keeps being reduced, physically became difficult.
With that, record layer like pie cloth repeating many layers, it meaning that the conception that is born, it records to each stratum, it does.
Don't you think? very it is bold conception.
The theoretical supporting as a research of the university has been born several years ago. Each university and the manufacturer cooperating in order to advance the " utilization ", (the commodity) in Photoelectronic Industry and Technology Developme, it researches and develops fundamental technology. Ricoh, to many layer with taking charge of the technology which " application of former optical system " it records & plays back in the record layer which is converted, researched and developed, advanced the one step to " of utilization ".
