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 80
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 81
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.

5. CONFIRM OPTICAL POWER SETTING PARAMETER LD Test result is ok, but Loader performance is bad. 1. Check ALPC parameter value 1) Press button to open ‘Results Display’ dialog. 2) Press button. ALPC Para - We can see optical power setting value. - Write optical Power Setting value to paper.
7. ATTACHMENT. OPTICAL POWER MEASUREMENT Optical Power measurement is to adjust LD power from Pick-up To measure optical power, LD status is on. Other light affects to optical power. Avoid other light to measure exact power Generally headlight power is about 50µW, Sun power is about 100mW. Optical Power measurement method 1.
