Hi im planin to purchase a sony dual dvd-rw player mainly to back up movies need some genuine reviews
&
Dual Layer Dvd-Rw and Regular Dvd-RW whats the diffrence??
Hi,
There is more space on a dual layer system. This makes it easier to make longer home movies and store more data. The dual-layer DVD+R system uses two thin embedded organic dye films for data storage separated by a spacer layer (see figure). Heating with a focused laser beam irreversibly modifies the physical and chemical structure of each layer such that the modified areas have different optical properties to those of their unmodified surroundings. This causes a variation in reflectivity as the disc rotates to provide a read-out signal as with commercially pressed read-only discs.
With dual layered, you have the ability to increase the bit rate of the video when authoring to get higher quality on the finished disc. Typical DVD authoring software applications use variable bit rate encoding to maximize utilization of the DVD disc space. By forcing the application to always encode at the highest bit rate supported, more space will be used on the disc, however, the quality difference is noticeable and worth it.
Here is an article that will help you better understand dual-layer DVD recording:
