20090116354 | Recording parameter setting device, program thereof, computer-readable recording medium containing the program, information recording medium, recording/reproducing device, and recording parameter setting method - A recording parameter setting device including a trial recording parameter setting section and a reproduced signal quality judging section. The reproduced signal quality judging section judges whether or not a reproduced signal obtained by reproduction of the trial recording carried out in accordance with the trial recording parameter satisfies a predetermined reproduced signal quality. If no, the recording parameters of the predetermined recording mark length or longer are further classified into detailed groups and trial recording is carried out again. If the reproduced signal satisfies the predetermined reproduced signal quality, the reproduced signal quality judging section sets the trial recording parameters as a recording parameter. This makes it possible to form a recording mark capable of surely providing a good reproduced signal quality while the number of recording parameters to be used is reduced. | 05-07-2009 |

20120218876 | Recording Parameter Setting Device, Program Thereof, Computer-Readable Recording Medium Containing the Program, Information Recording Medium, Recording/Reproducing Device, and Recording Parameter Setting Method - 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. | 08-30-2012 |
20120224467 | Recording Parameter Setting Device, Program Thereof, Computer-Readable Recording Medium Containing the Program, Information Recording Medium, Recording/Reproducing Device, and Recording Parameter Setting Method - 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. | 09-06-2012 |

20120127840 | INFORMATION RECORDING MEDIUM, RECORDING/REPRODUCING DEVICE, RECORDING/REPRODUCING DEVICE CONTROL METHOD, RECORDING/REPRODUCING DEVICE CONTROL PROGRAM, AND COMPUTER READABLE RECORDING MEDIUM - In an optical disc ( | 05-24-2012 |
20120183277 | INFORMATION RECORDING MEDIUM, REPRODUCTION METHOD AND RECORDING METHOD USING INFORMATION RECORDING MEDIUM, INFORMATION RECORDING/REPRODUCTION DEVICE, AND 3D CONVERSION UNIT AND INFORMATION RECORDING DEVICE - 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. | 07-19-2012 |
