ABSTRACT:
An optical recording and reproducing apparatus and a method for determining a write strategy thereof, includes a pickup part to record record data by irradiating a light on an optical disc, a driving part to operate the pickup part to irradiate the light corresponding to a predetermined optical parameter, an optical parameter variation part to vary the parameter within a predetermined variation range by a certain unit and to output the parameter to the driving part, a parameter determination factor measurement part to measure a parameter determination factor based on signals output from the pickup part, and a control part to determine a middle point between a maximum point and a minimum point of the optical parameter, within a range where the measured parameter determination factor does not exceed a reference value, as a final parameter. Accordingly, an optimal write strategy, in which the optical determination factor does not exceed the reference value, may be determined.
