Abstract
A method of and apparatus for recording data on an optical recording medium form a mark or a space by using a recording waveform having an erase pattern containing a multi-pulse. The method and the apparatus prevent distortion of the mark or the space and improve a mark shape such that a recording/reproducing characteristic of the optical recording medium is improved.
Claims16
A method of recording data on an optical recording medium, the method comprising:
- generating channel modulated digital data;
- generating a recording waveform having an erase pattern containing a multi-pulse and a recording pattern in response to the channel modulated digital data;
- and
- forming a first level of the channel modulated digital data as a mark and forming a second level of the channel modulated digital data as a space by using the generated recording waveform.
A method of recording data on an information storage medium, the method comprising:
- generating channel modulated digital data;
- generating a recording waveform comprising a recording pattern, an erase pattern having a multi-pulse, and a cooling pulse concatenating the recording and erase patterns, in response to the channel modulated digital data;
- and
- forming a first level of the channel modulated digital data as a mark and forming a second level of the channel modulated digital data as a space by using the generated recording waveform.
