Title (EN) OPTICAL INFORMATION MEDIUM, RECORDING AND REPRODUCTION APPARATUS, AND RECORDING AND REPRODUCTION METHOD
(FR) SUPPORT D'INFORMATIONS OPTIQUE ET APPAREIL ET PROCEDE D'ENREGISTREMENT ET DE REPRODUCTION
Abstract: front page image
(EN)A recordable optical information medium includes a recording area(104) including a guide groove (105) on which a recording material layer is provided for forming at least one recording mark which represents first information modulated by a first modulation system; and a pit area (102) including at least one concave and convex type pit (106) which represents second information modulated by a second modulation system. The guide groove and the at least one pit have substantially the same depth. The first modulation system and the second modulation system are different from each other.
(FR)L'invention concerne un support d'informations optiques enregistrable comportant une zone d'enregistrement pourvue d'une rainure de guidage sur laquelle est appliquée une couche de matériau d'enregistrement servant à former au moins une marque d'enregistrement représentant les premières informations modulées par un premier système de modulation; et une zone de dépression comportant au moins une dépression de type concave et convexe représentant les secondes informations modulées par un second système de modulation. La rainure de guidage et la dépression ont sensiblement la même profondeur. Le premier système de modulation et le second système de modulation sont différents l'un de l'autre.
