摘要： The present technology relates to a disk-type recording medium, a recording apparatus, a recording method, a reproducing apparatus, and a reproducing method, which are capable of recording, for example, data with high density and reproducing data recorded with high density robustly.
In the disk-type recording medium, synchronization patterns for synchronization are recorded in two adjacent tracks with a shift in a track direction so that positions in the track direction do not overlap. The present technology can be applied to, for example, optical discs, other disk-type recording mediums, and the like.

摘要： The invention provides an information recording device, an information reproducing device, and an information recording medium capable of securely protecting copyright of main information, and preventing illegal access to the recorded main information. The information recording device (3) is provided with a medium unique information generating section (9) that generates second sub information by data-converting stamper unique information based on disc identification information that differs for each optical disc after transferring main information and first sub information from a stamper (1') having the main information and the first sub information recorded therein onto an optical disc (1), and a medium unique information recording section (10) that records the second sub information in the optical disc (1) having recorded therein in advance the main information and the first sub information in a form different from the forms of the main information and the first sub information.

摘要： The present invention provides a recording medium and a recording/reproducing apparatus which enable the number of data units of recording pulse information to be reduced by dividing the recording pulse information into 1 byte-parameter information and differences from a value thereof, and the recording pulse information to be recorded on an existing DI area. A recording medium (801) has an information area (101) in which is recorded, as recording/reproducing control information, set values of a recording pulse adopted when forming a recording mark including: preceding space-based set values that include a first reference value that is a set value of a recording pulse corresponding to a predetermined preceding space and a first difference set value which is a set value of a recording pulse corresponding to a space other than the predetermined preceding space and which is expressed as a difference from the first reference value; and trailing space-based set values that include a second reference value that is a set value of a recording pulse corresponding to a predetermined trailing space and a second difference set value which is a set value of a recording pulse corresponding to a space other than the predetermined trailing space and which is expressed as a difference from the second reference value.

摘要： A configuration for preventing a recording error when a data recording process is performed on both lands and grooves of an optical disc is realized. An information processing device includes a data processing unit configured to control a data recording process on both lands and grooves of an optical disc. The data processing unit performs a process of detecting or matching positions at which data recording states of grooves or lands on both sides adjacent to a data recording target land or groove match when data are recorded on the lands or the grooves. The data processing unit performs, for example, a dummy data recording process or a skipping process as the process of matching the data recording states of the grooves or the lands on both sides adjacent to the data recording target land or groove.

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： Methods and devices for coherent holographic data channel techniques are presented. Coherent techniques for data detection generally include homodyne and heterodyne detection. Techniques for quadrature homodyne detection, resampling quadrature homodyne detection, n-rature homodyne detection, and spatial wavefront demodulation are presented. Coherent detection techniques in turn enable coherent channel modulation techniques such as phase modulation (including binary phase shift keying, or BPSK; phase quadrature holographic multiplexing, or QPSK; and quadrature amplitude modulation, or QAM). Coherent detection may also enable or improve the performance of other channel techniques such as partial response maximum likelihood (PRML), the various classes of extended PRML, and of noise-predictive maximum likelihood (NPML) detection.
