(JA) 情報記録媒体、情報再生装置及び方法、並びに、情報記録媒体の製造装置及び方法
Abstract:
(EN) An information recording medium (100) is provided with (i) a first information recording area wherein a first track for reproducing first information based on a first track pitch is formed by a laser beam, and (ii) a second information recording area wherein a second track for reproducing second information based on a second track pitch different from the first track pitch is formed by a laser beam. In the second track, a recording mark is previously recorded.
(FR) La présente invention concerne un support d’enregistrement de données (100) comprenant (i) une première zone d’enregistrement de données dans laquelle une première piste de lecture de premières données selon un premier pas transversal est formée par un faisceau laser, et (ii) une seconde zone d’enregistrement de données dans laquelle une seconde piste de lecture de secondes données selon un second pas transversal différent du premier est formée par un faisceau laser. Dans la seconde piste, un repère d’enregistrement est préalablement gravé.
(JA)  情報記録媒体(100)は、(i)レーザ光によって、第1情報を第1トラックピッチに基づいて再生するための第1トラックが形成された第1情報記録エリアと、(ii)レーザ光によって、第2情報を第1トラックピッチとは異なる第2トラックピッチに基づいて再生するための第2トラックが形成された第2情報記録エリアとを備え、第2トラックに、記録マークが予め記録されている。
