Japanese electronics maker Pioneer announced Monday it has developed a read-only optical disc with a capacity of 400 GB, which is far more than any optical discs currently available.
The optical disc has 16 layers; each of them can store 25GB of data, which is the maximum of a one-sided Blu-ray disc used to store high-definition video.
About 48 hours of high-definition content would be able to be held on these discs. For example, an entire season of a television program or mini-series could fit on a single disc.
The company said these discs can also be read by Blu-ray players after tweaking the hardware.
The growing storage needs of business and consumers are expected to drive demand for higher capacity discs. In addition, offering one disc equal to many commercially available discs today will conserve resources, Pioneer said in a statement issued from Japan.
"This development has bolstered Pioneer's confidence in the feasibility of a large-capacity optical disc, which is expected to become necessary in the near future," the company said.
Pioneer plans to release the details of its research at the International Symposium on Optical Memory and Optical Data Storage scheduled for July 13 in Hawaii.
