摘要： A method and apparatus to reproduce and/or record data from and/or to an optical recording medium. The method includes detecting a wobble signal from the optical recording medium, predicting a wobble channel state from the detected wobble signal, detecting an information signal from the optical recording medium, predicting an information channel state from the detected information signal. If a damaged section is discovered from the optical recording medium, the information signal is decoded based on the information on the wobble channel state or the information on the information channel state. Accordingly, data can be reproduced more effectively by predicting a channel state of an information (RF) signal and a channel state of a wobble signal.

摘要： The present invention is to realize a proper inner zone layout in a quadruple-layer disk.A test area is provided in the inner zone (inner circumference side area) in each of recording layers. If two test areas closer to the outer circumference, of four test areas, are defined as a first pair and two test areas closer to the inner circumference are defined as a second pair, the test areas of the first pair and the test areas of the second pair are so disposed as to be prevented from overlapping with each other in the layer direction. Two test areas of the first pair have the same consumption direction of the test area, and are so disposed that the areas to be used next hardly overlap with each other in the layer direction. Two test areas of the second pair have the same consumption direction of the test area opposite to the consumption direction of the test area in the first pair, and are so disposed that the areas to be used next hardly overlap with each other in the layer direction.
