2) Recording format using organic dye material ( DVD-R / DVD+R ) The format that records data through the creation of recorded marks by changing the organic dye material with a laser beam. Disc structure Recording principles [ Recording ] Recording is done by changing the organic dye layer and the substrate with a laser When a strong laser is applied to a disc, the temperature of the organic dye material goes up, the dye is decomposed and the substrate changes at the same time.
Page 86
3) Recording format using phase-change recording material ( DVD-RW / DVD+RW ) • Data is recorded by changing the recording layer from the amorphous status to the crystalline status, and played back by reading the difference of the reflection coefficient. Amorphous: Non-crystalline.
Page 87
To make recordings, it is necessary to modulate the write pulse, which is called “Write Strategy”. There can be many types in Write Strategy. Typically Write Strategy for DVD ±R has NMP(Non Multi-Pulse) type and MP(Multi-Pulse) type. In NMP type each single mark is created by subsequent separated short pulses. In MP type each single mark is created by one continuous pulse.
