Optical disc recording/reproducing apparatus and a method for determining write strategy thereof

A method for determining a write strategy for an optical recording and reproducing apparatus, comprising:

• varying an optical parameter within a predetermined variation range by a certain unit and outputting the varied optical parameter;
• irradiating a light corresponding to the varying optical parameter to record record data on an optical disc;
• generating reproduction data by reproducing the recorded record data;
• comparing the record data with the reproduction data to measure a parameter determination factor;
• abstracting a maximum point and a minimum point within a range where the measured parameter determination factor does not exceed a reference value;
• and
• determining a middle point between the maximum point and the minimum point as a final optical parameter.

An optical recording and reproducing apparatus comprising:

• an optical parameter variation part to vary an optical parameter within a predetermined variation range by a certain unit and to output the varied optical parameter;
• a pickup part irradiating a light corresponding to the varied optical parameter to record record data on an optical disc;
• a data reproduction unit to generate reproduction data by reproducing the recorded record data;
• a measuring unit comparing the record data with the reproduction data to measure a parameter determination factor;
• and
• a control unit to abstract a maximum point and a minimum point within a range where the measured parameter determination factor does not exceed a reference value, and to determine a middle point between the maximum point and the minimum point as a final optical parameter.

A method for determining a write strategy for an optical recording and reproducing apparatus, comprising:

• recording record data by irradiating a light on an optical disc;
• operating a pickup part to irradiate the light corresponding to a predetermined optical parameter;
• varying the predetermined optical parameter within a predetermined variation range by a certain unit and outputting a varied optical parameter to a driving part;
• measuring a parameter determination factor based on signals output from the pickup part;
• and
• determining a middle point between a maximum point and a minimum point of the predetermined optical parameter, within a range where the measured parameter determination factor does not exceed a reference value, as a final parameter.
