An optical disk () of the present invention includes (i) a medium information region () (a) in which type identification information is recorded by recesses and/or protrusions which are formed by a given modulation method and whose lengths are longer than a length of an optical system resolution limit of a playback device and (b) in which first address information is recorded in a first address data format and (ii) a data region () (a) in which content data is recorded by recesses and/or protrusions which are formed by the given modulation method and which include a recess and/or a protrusion whose length is shorter than the length of the optical system resolution limit and (b) in which second address information is recorded in a second address data format.

Method for playing back information recording medium

Information recording medium and reproduction device

A reproducing device () includes (i) an optical pickup () for irradiating, with reproduction light, an optical disk () which is a super-resolution medium, (ii) an RF signal processing circuit () for converting, into a reproduction signal, light which reflected off optical disk (), (iii) an i-MLSE detecting section () for evaluating quality of the reproduction signal, and (iv) a spherical aberration correcting section () for correcting a spherical aberration by using a result of evaluation of the quality of the reproduction signal.

Reproducing device

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

Carbon dioxide concentration control device and apparatus

Consumed energy and cost relating to control of a carbon dioxide concentration is reduced. Each of COconcentration control systems (to) includes a measuring unit () that measures a COconcentration, a COabsorption unit () that has a COabsorption material () for absorbing COat a rate depending on the temperature thereof, and a control unit () that controls the temperature of the COabsorption material () by using exhaust heat of a power system (), so as to control a COabsorption rate of the COabsorption material ().

Carbon dioxide concentration control system and carbon dioxide concentration control device

In a case where (i) a reflectance calculated from a reflected light amount obtained from a longest pit (Pmax) or a longest space (Smax) in a first pit row is defined as a first reflectance and (ii) a reflectance calculated from a reflected light amount obtained from a longest pit (Pmax) or a longest space (Smax) in the second pit row is defined as a second reflectance, the first pit row is formed such that the first reflectance becomes substantially identical with the second reflectance.

Optical information recording medium having first and second pit row of identical reflectance

A carbon dioxide concentration-controlling device (or) of the present invention controls the carbon dioxide absorption rate of a carbon dioxide-absorbing material () in accordance with a carbon dioxide concentration detected by a detector (). A state determining unit () determines a state of the carbon dioxide-absorbing material (), and a state controlling unit () controls the state of the carbon dioxide-absorbing material () to the state determined by the state determining unit ().
