FIELD: data carriers. ^ SUBSTANCE: in accordance to one of realization variants, in an optical disk processing method light reflected from optical disk is detected, which disk contains first and second recording layers, on each one of which first and second tracks are formed in turns starting from internal edge towards external edge (ST1), method for detecting pits is determined for first and second recording layers based on pit polarity information, which points at polarity of pits, included in information reflected in detected reflected light, and recording layer identification information, to identify first and second recording layers, and addresses are reproduced from pits in first and second recording layers by means of certain detection method (ST3-ST7). ^ EFFECT: increased efficiency. ^ 4 cl, 9 dwg |
