Test-write method, information recording method, and information recording apparatus

A test-write method for accurately and quickly determining recording conditions, and an apparatus suitable therefor. In a 2 T-based strategy, recording pulse conditions are determined by separately test-writing an even-number length mark and an odd-number length mark, and then the relative positions...

Summary:A test-write method for accurately and quickly determining recording conditions, and an apparatus suitable therefor. In a 2 T-based strategy, recording pulse conditions are determined by separately test-writing an even-number length mark and an odd-number length mark, and then the relative positions of the even-number length mark and the odd-number length mark at the recording pulse start time are adjusted.
