JVC has developed prototype read-only discs that can contain data stored in both the DVD and high-capacity Blu-ray Disc formats. They are the first discs that are able to contain data in both formats, a company spokesperson says. The discs contain three layers. The upper layer is a Blu-ray Disc layer with a capacity of 25GB. Below are two DVD layers with a combined capacity of 8.5GB, JVC says.
The company has not decided yet when the technology will be commercialized but JVC may produce the discs, says company spokesperson Fusako Adachi.
