摘要： In a recording/reproducing apparatus and a recording method, for enabling a high reliability on reproduction data are conducted the followings: recording a test mark within the test aria with a predetermined write strategy; obtaining signal amplitudes corresponding to a front portion, a middle portion, and a rear portion of the test mark, by reproducing the test mark; determining on whether the test mark has a desirable configuration or not, upon basis of at least one of ratios, defined between the amplitude of the front portion and the amplitude of the rear portion, and between the amplitude of the middle portion and the amplitude of the rear portion; correcting the write strategy if it is determined that the test mark has not the desirable configuration; and recording the information within the data area with the write strategy after the correction thereof.
