摘要： In an optical information storage medium reproduction apparatus (10) for reproducing an optical information storage medium including a plurality of information recording layers each including a recording mark having a length shorter than an optical system resolution limit, reproduction laser power for reading an information recording layer closest to a reproduction-laser-incident surface of the optical information storage medium is set to be lower than reproduction laser power for reading an information recording layer farthest from the reproduction-laser-incident surface but not lower than minimum reproduction laser power that satisfies a reproduction signal characteristic that the optical information storage medium reproduction apparatus (10) requires. With the arrangement, it is possible to prevent that the information recording layer closest to the reproduction-laser-incident surface is irradiated wrongly with reproduction laser having high reproduction laser power, thereby making it possible to obtain successful reproduction quality. That is, it is possible to realize the optical information storage medium reproduction apparatus (10) that can set optimum reproduction laser power and perform stable super resolution reproduction.

摘要： Where 3D conversion complementary information for 3D conversion of a TV program is pre-recorded on a first information recording area of an optical disc, a content recording area is set to an area on which the TV program relating to the 3D conversion complementary information is recordable. Where the 2D video content is pre-recorded on the first information recording area, download information, etc for recording the 3D conversion complementary information on a 3D conversion complementary information recording space is pre-recorded on a third information recording area so that 2D video content can be reproduced as 3D video. This allows recording and viewing 3D video by easily converting 2D video content, without changing standards and communication formats of generally available 2D video contents and while suppressing an increase in distributed information amount caused by conversion to 3D video.

摘要： A recording parameter setting device setting parameters of pulse sequences forming recording marks on recording media. The device includes a storage section storing first and second look-up tables, and a recording parameter setting section for obtaining from the tables and setting parameters corresponding to recording information. The pulse sequences form at least marks equal to or longer than a first predetermined length but not longer than a maximum mark length, and include top and last sections. Also, the first lookup table stores parameters for top sections that control heat of front edges of marks classified into a same group. The second lookup table stores parameters for last sections for controlling heat of rear edges that are equal to or longer than a second predetermined recording mark length, that is longer than the first predetermined recording mark length, through the maximum recording mark length and classified into a same group.

摘要： A recording/reproducing device includes a laser and a laser drive carried by a pickup having a drive for movement. A control controls the drives to irradiate the recording medium with laser pulse sequences forming 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 recording parameters for top sections that are classified according to recording mark lengths and recording parameters of the first through the 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.

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.

摘要： In an information recording/reproducing device, a resting period (tm) is set to be constant regardless of a mark length of a recording mark and regardless of the number of divided recording pulses. Consequently, it is possible to provide an information recording device, an information recording method, and an information recording medium, each allowing formation of a recording mark with a uniform width by use of a low laser power and allowing reduction of the number of parameters for determining a recording waveform, when forming a long recording mark.
