ABSTRACT:
A test pattern including a first test mark which is one unit-record-length longer than a shortest mark among modulating codes and a second test mark which is two or more unit-record-lengths longer than the shortest mark is recorded under a plurality of recording conditions (step S2). The recorded test pattern is reproduced (step S3), and based on a plurality of reproduced signals thus obtained, recording conditions allowing the first test mark and the second test mark, respectively, to be suitably recorded are selected (step S4). A recording condition for the shortest mark is determined by inference based on the recording conditions of the first test mark and the second test mark.
