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.
Write Strategy for DVD RW has Type 1 and Type 2. In Type 1 the mark with nT width is created by one
top pulse and (n-2) mul- ti-pulses. Thus mark 3T is made by one top pulse and one multi-pulse. In Type 2
the mark with nT width is created by one top pulse and (n-3) multi-pulses. Thus mark 3T is made by one top
pulse only.
RV9 uses MP type Write Strategy for DVD R and Type 1 for DVD RW as shown below.
