FIELD: physics, computing science.
SUBSTANCE: information carrier and method of data recording on data carrier and/or data reproduction from data carrier are suggested, meanwhile the data carrier has at least one layer of data storage. Data is recorded in the form of jutted or pressed elements of the record in or fractional field of the data carrier, and information related to jutted and pressed elements of the record is recorded. Smooth tracking can be achieved by using data related to jutted and pressed elements of the record, that is, the information of reverse polarity.
EFFECT: decrease of time which is required to receive information about signal polarity by tracking.
