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.

摘要： A carbon dioxide concentration control device (10) is provided with a control unit (15) that controls an absorption amount of carbon dioxide of a carbon dioxide absorbent (16) per unit hour, and a regeneration control unit (14) that generates the carbon dioxide absorbent (16), and a second drive energy supply unit (13) which is different from a first drive energy supply unit (11) that supplies power to the control unit (15) supplies power to the regeneration control unit (14), and thus a carbon dioxide concentration in a space is controlled to be an appropriate value for long periods of time.
