摘要:
A display control device (2) disclosed includes (i) a display/non-display video image determining section (70) that determines, on the basis of (i) video image information about a video image displayed by a display device (400) and (ii) viewing mode information indicative of a viewer's desired mode of viewing a video image, whether the video image displayed by the display device (400) is a display video image or a non-display video image and (ii) a shutter operation control section (80) that closes a right-eye shutter and a left-eye shutter of a liquid crystal shutter (500) when a video image determined as a non-display video image, which is unnecessary for the viewing mode and which is thus not to be displayed to the viewer, is displayed by the display device (400). The display control device (2) thus closes the right-eye shutter and the left-eye shutter of the liquid crystal shutter (500) when a non-display video image is displayed by the display device (400). This arrangement allows each viewer to view a video image in a mode suitable for the viewer.

摘要:
There are provided at least a first information storage area 20A and a second information storage area 40A. The first information storage area 20A contains, in advance, an OS or mpeg data. The second information storage area 40A is either write-once or rewriteable and available for writing OS update information or movie correction information. The configuration enables easy backup and restoration of software, content, and various information including update information for use by the software and content with reduced user time and workload.

An invention disclosed includes a layer number obtaining section (222) for determining which information storage layer (L1) has been accessed and a layer type identifying section (223) for identifying a type of the information storage layer (L1) determined by the layer number obtaining section (222). With the configuration, even in a case where an information recording and reproducing apparatus accesses an information storage layer different from an intended information storage layer by false operation or the like, it is still possible to dissolve mismatching between a recording or reproduction control scheme being set up and a recording or reproduction control scheme suitable for the information storage layer thus accessed.

摘要:
The present invention provides an optical information recording medium (2) capable of shortening a time from acquiring identification information to starting a program etc. recorded on an ROM layer. The optical information recording medium (2) includes two or more information recording layers, information of each of the two or more information recording layers is readable by emitting reproducing light thereto, at least one of said two or more information recording layers is an RE/R layer (4), at least another one of said two or more information recording layers is an ROM layer (5), and the RE/R layer (4) includes an identification information recording region (41), and an interlayer-movement Flag is recorded on the identification information recording region (41).
摘要:
An optical information recording medium (1) includes, on a substrate (50), a ROM layer (20), a RE layer (40), an intermediate layer (30) separating the ROM layer (20) and the RE layer (40), and a cover layer (10) provided in a position farthest from the substrate (50). The RE layer (40) is an information recording layer provided in a position farthest from the light transmitting layer and also is a recording layer of disc type identification information and an individual identification number recorded in a format allowing easier determination as compared to an information recording format used in the layer allowing only readout of information by use of light irradiation.Therefore, it becomes easy to check a disc type in a recording/reproducing device and one recording/reproducing device can be shared with other types of optical disks. Further, disk production becomes easy. In addition, it becomes possible to obtain an optical information recording medium that makes it possible to replace outdated data in the ROM layer by recording, in the RE layer, updated data obtained at the time when net connection can be established.

An optical information recording medium (1) includes on a substrate (50), a ROM layer (20), a RE layer (40), an intermediate layer (30) separating the ROM layer (20) and the RE layer (40), and a light transmitting layer (10) provided farthest from the substrate (50). The RE layer (40) is an information recording layer provided most farthest from the light transmitting layer (10), and is a recording layer of BCA recorded in a format easily determinable as compared to an information recording format used in the ROM layer (20), and antifouling property of a surface of the light transmitting layer (10) is set based on the RE layer (40). This makes it easy for the recording and reproducing apparatus to confirm a disc type, allows for sharing one recording and reproducing apparatus with other types of optical discs, and simplifies the disc production. Furthermore, an optical information recording medium is accomplished, in which outdated data on the ROM layer is replaced by recording, on the RE layer, updated data obtained while Internet connection can be established.
摘要:
Recording mark forming method utilizing a device including a laser and a laser drive carried by a pickup having a movement drive wherein a control controls the drives to irradiate a recording medium with laser pulse sequences to form recording marks having recording mark lengths between a predetermined and maximum lengths, a top section, a last section including a cooling period, and an intermediate period. Heat of mark front edges is controlled by top section recording parameters classified according to recording mark lengths and recording parameters of first through maximum recording mark lengths are classified into a same group. Heat of mark rear edges is controlled by cooling start positions for cooling periods classified according to recording mark lengths. Cooling start positions for a second predetermined mark length through the maximum mark length are classified into a same group. The second mark length is longer than the first mark length.
