摘要： A recoding playback apparatus and an optical disk are provided that allows reduction of a low frequency noise at a time of playback of a super resolution optical disk including small record marks whose size is below the diffractive limitation, to enhance quality of a playback signal. [Means for solution] The reflective beams from the optical disk are received by dividing into outer portion beams and a center portion beam, and a playback signal is created by combining such beams based on respective different gains. Based on received amounts of light or amounts of low frequency noise in respective light receiving regions, adjustment or determination of gain values is made, or the optical head apparatus is optically adjusted, whereby the low frequency noise is optimally suppressed. Further, a specific region is provided on the optical disk for making the foregoing adjustment.

摘要： An optical disc according to an embodiment of the present invention comprises at least three layers of recording layers that each record information in an information track. The recording layer comprises: an inner circumferential side region positioned on the inner circumferential side; a data region which is positioned to the outer circumferential side of the inner circumferential side region and records content information; and an outer circumferential side region positioned to the outer circumferential side of the data region. The content information is recorded in the data region of the three or more layers of recording layers, and a point on an upper layer and a point on a lower layer one layer below the upper layer at which playback switches from content information of the upper layer being played back in an inner circumferential direction to content information of the lower layer, are set so as to be more to the outside than an innermost circumferential position of the data region.

摘要： An optical information recording medium includes at least one recording layer, a protective layer that transmits a focused laser beam, and a super-resolution functional layer that changes an optical characteristic in a local region smaller than the diffraction limit determined by the optical performance of the focusing optical system and the wavelength of the laser beam during at least the period of irradiation by the focused laser beam. The maximum thickness ( K ) between the light incidence surface of the protective layer and the recording layer is 0.083 mm.

摘要： An optical read/write apparatus causes a read/write light beam from illuminating means to strike only one side of an optical storage medium including stacked data storage layers each of which is readable/writeable separately from the other layers. In this case, the optical read/write apparatus operates so that data is read/written from/into a second data storage layer (8) after fully recording a recordable area of a first data storage layer (10). Thus, light can be shone with uniform intensity across the substantially entire recordable area of the second data storage layer without using a complex read/write system even under such conditions that the transmittance to light of the first data storage layer in the recordable area may vary depending on whether any data is recorded in the recordable area.
