FIELD: physics, computer engineering.
SUBSTANCE: invention is related to the field of information carriers with multilayer structure and methods of data reading. Carrier comprises the first recording layer containing original area, the first user section located downstream original area and intended for storage of user data, and the first section of transition located downstream the first user section; the second recording layer superimposed on the first recording layer and comprising the second section of transition, the second user section located downstream the second section of transition and intended for storage of user data, and final section located downstream the second user section, besides, original area of the second transition section follows after final address of the first transition section. Method for data reading consists in reading of final address of the first user section from original area and number of sectors in the first and second sections of transitions; reading of current address of sector, detection of current address location by final address of sector and, afterwards, the following recording level is selected, current address of sector is interpreted, initial address of the second user section in the second recording layer is calculated and found by final address of the first user section with application of procedure of transformation for provision of sequential reading of user data.
EFFECT: increase of carrier capacity and reduction of time required for data reading.
