ABSTRACT:
A write pulse generating apparatus includes a control unit which provides information on an optical recording medium type and information on a recording speed factor, and a control signal generating unit which determines a multi-pulse type which is to be generated in a multi-pulse interval based on the information recording medium type and recording speed factor. The generating unit generates a signal for controlling the light emitting device driving unit to generate a write pulse having the determined multi-pulse type. A control unit sets the level of the write pulse for up to an entire interval of a write mark and/or a write space according to the optical recording medium type and the recording speed factor.
