| 20080225659 | Information Recording Apparatus and Method, and Computer Program - A disc-shaped information recording medium has a first and a second recording layer. A buffer area is arranged adjacent to a recording area of each of the layers for preventing deviation of the recording position onto/from each of the layers. A first part of the information is written along a first track path on the first recording layer, a predetermined amount of first buffer data in a part of the buffer area of the first recording layer is written into the first recording layer, and inter-layer jump is performed from the first recording layer to the second recording layer. A predetermined amount of second buffer data in the buffer area of the second recording layer is written in the second recording layer and write element is controlled to write a second part of the information to be recorded, on the second recording layer by changing the recording direction. | 09-18-2008 |
| 20080232226 | Information Recording Apparatus and Method, and Computer Program - An information recording apparatus has: a recording device for recording information onto an information recording medium, whose recording speed can be changed to first and second linear velocities, by irradiating laser light with a variable recording power; a measuring device for measuring reproduction quality by reproducing the record information recorded at the first linear velocity, if the recording speed is changed from the first linear velocity to the second linear velocity; a first calculating device for calculating a link power which is the recording power which gives the reproduction quality measured by the measuring device in the second linear velocity, on the basis of correlation information for representing a correlation between the recording power in the second linear velocity and the reproduction quality of the record information; and an adjusting device for adjusting the recording power at a time in stages or in continuity. | 09-25-2008 |

| 20080291804 | Information Recording Layer of Optical Disc and Optical Disc - An optical disk includes a substrate covered with an information recording layer. The information recording layer includes a recording material and a dispersion material dispersed in the recording material. The recording material absorbs recording light for recording information, and then generates heat. As the light refraction index of the recording material changes due to the heat generation, information is recorded on the recording material. The dispersion material has lower absorptance of the recording light and lower thermal conductivity than the recording material, and an external dimension smaller than a diffraction limit of reading light for reading information. | 11-27-2008 |

| 20090080324 | Information Recording Layer of Optical Disc, Optical Disc and Disc Device - An optical disk includes a substrate covered with an information recording layer. The information recording layer includes a recording material and an exothermic material dispersed in the recording material. The exothermic material absorbs recording light for recording information, and then generates heat. An external dimension of the exothermic material is smaller than the diffraction limit of reading light for reading information. The recording material has absorptance of a wavelength of the recording light lower than that of the exothermic material. Information is recorded on the recording material as the light refraction index of the recording material changes due to heating. | 03-26-2009 |
