Nero announced that its applications, Nero Burning ROM and Nero Express, now support Layer-Jump Recording (LJR) of dual-layer DVD-R media, thus permitting multi-session burning. OEM customers can immediately benefit from this new technology by downloading an update online through the Nero website available mid-June.

Nero' s Layer-jump recording (LJR) provides multi-session burning of dual-layer DVD-R media. In other words, data can be added to a medium over several burning sessions, with the sessions appearing in the sequential order in which they were originally recorded. Both Nero and the burner manufacturer?s firmware previously only supported disc-at-once (DAO) mode meaning data could be written to a DVD-R only one time.

Unlike dual-layer recording, in which data is first written to one layer and then to the other, layer-jump recording alternates between both layers during the burning process, thereby evenly distributing the data between both layers. The written area of both layers expands evenly outwards with each burning session. According to Nero, the fact that adjacent layer areas always contain data, is resulting in a reduction in background noise, better signal quality, and higher read compatibility. Of course, this is a theoritical approach and we should wait for the first tests to see the compatibility of the multi-session DVD-R double layer media.
