| 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 |
