发明名称 光記録媒体および再生方法
摘要 An optical recording medium includes: a medium information region on which medium identification information is recorded; a content region on which content information is recorded; and a blank region provided between the medium information region and the content region and in which at least two tracks are provided so as to connect a train of prepits in the medium information region and a train of prepits in the content region. No information is recorded on the blank region. Thus, an optical recording medium is provided in which a region on which medium identification information is recorded and a region on which content information is recorded are different in track pitch and in which a reproduction error hardly occurs when reproduction shifts from the region on which the medium identification information is recorded to the region on which the content information is recorded.
