| 20100110850 | INFORMATION RECORDING MEDIUM, INFORMATION RECORDING METHOD AND INFORMATION RECORDING APPARATUS - OPC areas are used for adjusting recording parameters (power and strategy). In an optical disc including two recording layers, the recording power for one recording layer is likely to be influenced by a transmittance variance or the like provided by the recording state of the other recording layer (either already recorded or unrecorded). In addition, recording is performed while changing the power. For these reasons, the OPC areas are located so as not to be at the same radial positions among the recording layers. However, as the number of recording layers is increased, the area size for securing the OPC areas is increased, which may undesirably lead to an increase of the lead-in zone or the lead-out zone (decrease of the user data zone) and a decrease of the OPC area size in each recording layer (decrease of the number of times of usage by the user). According to the present invention, an area for power calibration in which recording is performed while changing the power and so which is significantly influenced by the transmittance balance, is separated from an area for strategy calibration or the like in which recording is performed at a fixed power suitable to the disc and so which is unlikely to be influenced by the transmittance balance. Only power calibration areas are located at different radial positions among different recording layers so as not be influenced by the recording state of the other recording layers, and the strategy calibration areas are located so as to include the same radial position among different recording layers. | 05-06-2010 |

| 20110107134 | INFORMATION RECORDING MEDIUM, METHOD FOR RECORDING INFORMATION ON INFORMATION RECORDING MEDIUM, METHOD FOR REPRODUCING INFORMATION FROM INFORMATION RECORDING MEDIUM, AND METHOD FOR MANUFACTURING INFORMATION RECORDING MEDIUM - The present invention provides a measure for getting read/write control information stored within a space of a predetermined size in a format that ensures compatibility with media of a lower order or an older generation even if the size of the read/write control information increases significantly as the storage densities of information storage media rise in the near future. On an information storage medium, a data sequence is writable as a combination of marks and spaces. The medium has at least one information storage layer, which has an information storage area to store information and a control information area for use to perform a read/write operation on the at least one information storage layer. The control information area stores at least one set of control information, which includes a first kind of write pulse information including information to be used as a reference value and a second kind of write pulse information including information to be used as an offset value. If the pulse width or pulse position of a write pulse is definable with a precision of 1T/n (where T is a channel clock pulse width and n is a positive integer), the size of the offset value is large enough to define at least an n/2 range. | 05-05-2011 |
| 20110110214 | INFORMATION RECORDING MEDIUM, INFORMATION RECORDING METHOD, INFORMATION RECORDING APPARATUS, INFORMATION REPRODUCING METHOD AND INFORMATION REPRODUCING APPARATUS - If a defective cluster in a spare area is managed with a defect entry, the size of a DFL will increase as the size of the spare area increases with an increase in the number of recording layers stacked in a disc. An information recording medium according to the present invention has pointer information indicating the location of the next available cluster in each spare area, and restricts the direction in which the spare area is used. Also, a defect entry indicating a defective cluster in the spare area is registered with the DFL. Thus, even if the size of the spare area | 05-12-2011 |
| 20110122748 | WRITE-ONCE READ-MANY INFORMATION RECORDING MEDIUM, INFORMATION RECORDING METHOD, INFORMATION REPRODUCTION METHOD, INFORMATION RECORDING APPARATUS, AND INFORMATION REPRODUCTION APPARATUS - A write-once read-many information recording medium is provided, which is capable of easily searching for a latest DDS and a latest defect list. At least one disc management working area is sequentially allocated in a predetermined direction on the write-once read-many information recording medium of the present invention. The latest defect list and the latest DDS are provided in a recorded disc management working area neighboring a border between the recorded disc management working area and an unrecorded disc management working area, where the latest defect list precedes the latest DDS in the predetermined direction. | 05-26-2011 |
| 20110145524 | INFORMATION RECORDING MEDIUM, INFORMATION RECORDING DEVICE, INFORMATION RECORDING METHOD, INFORMATION REPRODUCING DEVICE, AND INFORMATION REPRODUCING METHOD - According to the present invention, the size of defect management information is reduced by using a top spare area | 06-16-2011 |
