PHILIPS DVD+RW

RM100.00

Philips’ DVD+RW Video technology also offers easy-to-use-editing facilities. Whereas editing private camcorder material on conventional equipment generally requires two video devices, random access to a DVD+RW disc means editing can be done using a single DVD Video Recorder. This brings editing within reach of the average consumer and makes it quick and very easy to use.

In DVD+RW, data is arranged on a disc according to the industry-standard UDF (Universal Disc Format) standardized and published by OSTA (Optical Storage Technology Association). UDF is well suited to handling file changes and (random) writing of small amounts of data, and facilitates the design of multiplatform applications. Today, UDF is increasingly used for writing to CD-RW discs instead of the less flexible ISO9660 file system format that was developed to handle read-only data applications. Virtually platform-independent, UDF makes DVD systems highly compatible with CD-based data systems. Also, being designed to handle the massive capacities of future optical storage systems, UDF provides excellent forward compatibility.
