PROBLEM TO BE SOLVED: To provide an information signal recording method by which the correlation between adjacent tracks can be removed, by using a part of scramble signal redundantly. SOLUTION: In the information signal record method in which an information signal S3 is made to scramble with a scramble signal S2, a part of the scramble signal is used redundantly when recording the information signal S3 on information recording medium 5 having circumferential information tracks. This allows the correlation between adjacent tracks to be removed and stable tracking control to be obtained.
