摘要： An optimum power set value Pwp1 for Layer 1 obtained by an OPC is used as an initial value Pw21 of the OPC for Layer 2. At this time, an inclination Ia is obtained from an approximation line of a β value for Layer 1 (recording power to the β value) obtained by the OPC. From the β value obtained by performing a test recording at the initial value Pw21 and the inclination Ia, an approximation line of a β value for Layer 2 (recording power to the β value) is obtained. Then, on the obtained approximation line, a laser power for providing a target β value (βt) is obtained, and set as an optimum power Pwp2 for Layer 2. Thus, an optimum power setting conforming to characteristics of a disc can be performed. As a result, setting the optimum power for Layer 2 can be performed more smoothly and quickly.

摘要： The first layer (DVD layer) is first reproduced using the red layer light. Thereafter, search for the second layer (HDDVD layer) is performed with the blue laser light in accordance with the reproducing operation being temporarily interrupted for menu display (display for chapter or language selection). If the second layer is detected, a display indicating that the second layer can be selected is displayed over the menu display. If instruction to reproduce the second layer is input from the user according to the display, the reproducing operation of the first layer using the red laser light is switched to the reproducing operation of the second layer (HDDVD layer) using the blue laser light.

摘要： Provided is an optical disc device in which adjustment precision of recording laser power is improved without complication of a processing sequence during recording operation. In response to a recording start instruction, OPC is executed using an inner disc drive zone to set an initial value of recording laser power Pws. Then, when a recording instruction REC(1) is issued, recording is successively performed from the head of a data area using the laser power Pws. After that, when an intermittent standby period T is set, sample data is recorded at the number of times corresponding to the intermittent standby period T in a next recording position, and R-OPC is executed. Therefore, the recording laser power Pws is set again. Then, when a second recording instruction REC(2) is issued, recording is successively performed from a next recording position, that is, a position next to an end portion of data recorded by the first recording instruction REC(1) using the reset laser power Pws. At this time, data corresponding to a head portion of the second recording instruction REC(2) is overwritten on sample data in the head of the recording position.

摘要： An apparatus for recording and reproducing data on a storage medium and a recording method for recording data in a storage medium. The recording of a new information item is permitted on the condition that the total number of slots managing the unrecorded parts and the recorded parts is smaller than the predetermined number of slots. The start and end addresses of the part to be erased are compared with the respective end and start addresses of the unrecorded parts; and, if there are any consecutive addresses, two parts are joined at a boundary between consecutive addresses. The joined parts set to correspond to one slot which includes the entire new unrecorded part. A memory area corresponding to addresses of the data storage area is allocated to a work memory. Small areas divided by respective start and end addresses of the recorded parts are extracted from the memory area. Then the memory area is provided with portions left by the extraction as unrecorded areas, and start and end addresses of the unrecorded parts are stored into empty slots.

摘要： The number of recording layers of the loaded disc is determined using the blue laser light. If the number of recording layers is two, drawing is performed in the recording layer on the near side when seen from the laser light entering side, and demodulation is performed with the HDDVD decoder. If demodulatable, the disc is determined as a disc in which two HDDVD layers are arranged. If not demodulatable, determination is made on whether or not the data of the recording layer is demodulatable with the DVD decoder. If demodulatable with the DVD decoder, the laser light is switched to the red laser light and the number of recording layers is determined. If two recording layers are detected in this determination, the disc is determined as a disc in which two DVD layers are arranged. On the other hand, if one recording layer is detected, the disc is determined as a hybrid HDDVD in which one HDDVD layer and one DVD layer are arranged.

摘要： When a disc loaded on a player is a hybrid next generation DVD, determination is made on whether the connected TV device is adaptable for the HD mode. Such determination is performed by whether or not the copyright protecting function of the connected TV device satisfies a condition set in advance. When adaptable for the HD mode, reproduction prioritizing the HDDVD layer is performed. When not adaptable for the HD mode, reproduction prioritizing the DVD layer is performed. Thus, the video content of HD mode recorded on the HDDVD layer is protected against leakage to the outside via the connected TV device by reproducing the DVD layer in preference in the case the copyright protecting function of the TV device is not sufficient.

摘要： An optimum power set value Pwp1 for Layer 1 obtained by an OPC is used as an initial value Pw21 of the OPC for Layer 2. At this time, an inclination Ia is obtained from an approximation line of a β value for Layer 1 (recording power to the β value) obtained by the OPC. From the β value obtained by performing a test recording at the initial value Pw21 and the inclination Ia, an approximation line of a β value for Layer 2 (recording power to the β value) is obtained. Then, on the obtained approximation line, a laser power for providing a target β value (βt) is obtained, and set as an optimum power Pwp2 for Layer 2. Thus, an optimum power setting conforming to characteristics of a disc can be performed. As a result, setting the optimum power for Layer 2 can be performed more smoothly and quickly.
