An apparatus and a method for generating an optical recording pulse having multi-pulse patterns suitable for high-density and high-speed optical media are provided. The apparatus includes a recording pulse generator (303) for generating an optical recording pulse; and a controller (301) for controlling the recording pulse generator so that according to the type of optical medium or the set recording speed, there are at least two different widths of the multi-pulses used to create one mark. Therefore, jitter is reduced and cross erasure between adjacent tracks, which may be caused by the domain configuration, is prevented in any high-density, high-speed recording environments. In addition, cross-talk between adjacent tracks, which may be generated due to the domain configuration during reproduction, can be prevented. |
