FIELD: information technologies.
SUBSTANCE: when making a disc, information is recorded to a site path and a groove path. Wobble is generated in such a manner so that initial direction of wobble, in case when the site path is selected as a path, where information is recorded, and initial direction of wobble in case, when the groove path is selected as a path, where information is recorded, are opposite to each other. Address information is added to wobble by means of MSK modulation (modulation with minimum shift) and HMW modulation (modulation with harmonic modulated waves) in respect to a signal of a reference wobble frequency
EFFECT: less time to start a device of recording and reproduction.
