An optical disc medium compares a track groove, along which main information is recorded. The track groove is divided into a plurality of blocks. The plurality of blocks each include a plurality of frames. The plurality of frames each include one shape of wobbles indicating sub information, among a plurality of prescribed shapes of wobbles. The plurality of blocks each have address information. The address information is represented by a string of at least one piece of sub information represented by the shape of wobbles of at least one of the plurality of frames.

Cette invention se rapporte à un support du type disque optique, qui comprend un sillon de piste, le long duquel sont enregistrées les informations principales. Ce sillon de piste est divisé en plusieurs blocs. Ces blocs contiennent chacun plusieurs trames. Ces trames contiennent chacune une forme d'oscillations indiquant des sous-informations, parmi plusieurs formes prescrites d'ondulations. Les blocs comportent chacun des informations d'adresse. Ces informations d'adresse sont représentées par une chaîne d'au moins une sous-information représentée par la forme des oscillations d'au moins l'une desdites trames.
