RECORDING CONDITION SETTING METHOD AND INFORMATION RECORDER USING SAME

摘要

A test pattern including a first test mark longer than the shortest mark of modulation codes by one recording unit and a second test mark longer than the shortest mark by two or more recording units is recorded on an optical disc under recording conditions (step S2). The recorded test pattern is reproduced (step S3). Recording conditions to favorably form the first and second test marks are set according to the obtained reproduced signals (step S4). The recording condition of the shortest mark is determined by inference under the recording conditions of the first and second test marks (step S5).
