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 162 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 163 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.

  • Page 173 6. Optical Power Setting Parameter Check Use when defective happens even though LD test result is normal. When defective can be found but power test result is OK, You need to check current settings whether they are proper or not. In this case, Pressing will display ALPC Parameter Info window and show current optical power settings recorded in EEPROM(IC302).

  • Page 175 Appendix. How to measure optical power Optical power measurement is measuring actual optical power coming out from an object lens with LD turned on. thus, In order to measure optical power, LD should to be turned on and environment need to be dark enough. If necessary, Cover the top side of the sensor with black paper or hand when measuring.
