ABSTRACT:
An optical disc writing condition determining method according to the present invention includes the steps of: performing a first test write operation at a low speed on an inner test track; setting condition A for performing a write operation at the low speed on the inner test track based on a result of the first test write operation; performing a second test write operation at the low speed on an outer test track; setting condition B for performing a write operation at the low speed on the outer test track based on a result of the second test write operation; performing a third test write operation at a high speed on the outer test track; setting condition C for performing a write operation at the high speed on the outer test track based on a result of the third test write operation; and calculating either a difference between the conditions A and B or a ratio of the condition B to the condition A and modifying the condition C based on the difference or the ratio, thereby determining writing condition D for performing a write operation at the high speed on user data tracks.
