DUAL-LAYER DISC
Here 2 layers of data are recorded on the same side where second layer can be accessed with a change in laser-beam’s angle.

DUPLICATION
Recording small quantity of DVD discs with a dedicated recorder.

DVD
DVD is the acronym for Digital Versatile Disc. This media which stores digital data is used in all types of DVD devices. They have longer life-span, random access and better video and audio quality.

ELECTRONIC PROGRAMMING GUIDE
