Difference between cdrom DVD rom?
Another big difference between DVD recording and CD recording is the recording format. DVD recording uses UDF – Universal Data Format. UDF makes it possible to store data, video, audio, or a mix of all three within a single physical file structure. This file structure ensures that any file can be accessed by any drive, computer, or consumer video. UDF includes the CD-standard ISO 9660 compatibility, but CDs do not comply with UDF.
