JVC develops world’s first single-sided, dual layer DVD-RW disc technology

JVC has developed the world’s first single-sided, dual layer DVD-RW disc technology with a maximum storage capacity of 8.5GB.
The breakthrough was made possible by the development of a high sensitivity recording film, a new recording method 'N-Strategy', which enhances erasability, and a proprietary precision thin film forming technology.
The new disc technology delivers 1.8 times the storage capacity of conventional, single-sided, single layer DVD-RW disc with a 4.7GB capacity. Each single-sided, dual layer DVD-RW disc can record up to 11 hours of video.
JVC has also developed a facing film bonding method that enables mass production of the new discs using conventional manufacturing equipment.
The company’s new disc technology adds rewritable features to single-sided, dual layer DVD discs, which until now have been limited to write-once capability. JVC predicts that the technology will enjoy widespread use in applications such as video recorders and optical drives for both mobile and desktop PCs.
The company will continue to develop feature enhancements aimed at future commercialisation of the technology. JVC will forward a proposal to the DVD Forum in an effort to promote the adoption and advancement of single-sided, dual layer DVD-RW disc technology.
