Recording/reproducing apparatus and method

A recording/reproducing method comprising:

• setting a predetermined length as an integer multiple of a unit recording length and setting a plurality of recording parameters with reference to mark/space combinations on an information storage medium which can be configured within the predetermined length ahead of a start point of a mark for recording data on the information storage medium and mark/space combinations which can be configured within the predetermined length behind an end point of the mark for recording data on the information storage medium;
• and
• recording the data on the information storage medium according to the plurality of recording parameters.

A method of optimizing a signal for recording on an optical disk, comprising:

• generating a recording signal having a predetermined waveform;
• and
• optimizing recording parameters of the recording signal while forming a series of marks on the optical disk based on mark/space combinations that can be configured within a predetermined length ahead of a start point of a mark for recording data on the optical disk and mark/space combinations that can be configured within the predetermined length behind an end point of the mark for recording data on the optical disk.

A recording/reproducing apparatus for recording on an optical disk, comprising:

• a writing/reading unit to write or read data to or from the optical disk;
• and
• a control unit to generate a recording signal having a predetermined waveform and to optimize recording parameters of the recording signal while forming a series of marks on the optical disk based on mark/space combinations that can be configured within a predetermined length ahead of a start point of a mark for recording data on the optical disk and mark/space combinations that can be configured within the predetermined length behind an end point of the mark for recording data on the optical disk.
