- Page 92 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.
