    摘要： An optical recording medium which is a multilayer optical recording medium including a plurality of recording layers and records or reproduces information by the irradiation of light having a wavelength of lambda 0. At least one recording layer out of a plurality of recording layers includes a variable absorption film. The variable absorption film contains a material in which an electron energy has a band structure, and the absorption end of an absorption spectrum moves toward a longer wavelength side with a rise in temperature when light is absorbed by transition between electron bands, has a first absorptance to light having a wavelength of lambda 0 when a film temperature is a first temperature (application environment temperature), and has a second absorptance higher than the first absorptance to light having a wavelength of lambda 0 when a film temperature is a second temperature higher than the first temperature.

    摘要： An apparatus and a method for writing a label on a surface of an object, such as on the top surface of an optical disk (CD, DVD, BIu Ray etc.) are disclosed. The label is written by using the laser in the optical pickup unit of the disk device. The laser light is emitted as a pulse train in order to reduce the thermal load on the laser. The pulse train is provided by controlling the supply current of the laser, and the radiation power of the laser is reduced to zero between two successive sub-pulses of the pulse train by turning off the laser between successive sub-pulses.

    摘要： A disc-like optical recording medium (100) comprising:
    a recording layer (107,L1) configured to record or reproduce information by light with a predetermined wavelength;
    a burst cutting area (BCA) provided on the recording layer (L1) at an inner peripheral side of the medium (100), the burst cutting area (BCA) being configured to record specific information (BCA) including a mark polarity flag, for specifying a polarity of recording marks on the recording layer (L1), wherein
    the mark polarity flag indicates that the polarity of the recording marks is low-to-high or high-to-low.
