    摘要： When writing data to a normal-density CD-R, data linking blocks including two run-out blocks are appended to each packet of the data, and the data is interleaved with a maximum delay of 108 frames. On the other hand, when writing data to a double-density CD-R, data linking blocks including three run-out blocks are appended to each packet of the data, and the data is interleaved with a maximum delay of 189 frames. There are provided a data recorder, data recording method, data player, data playback method, and an optical disc with which data can properly be written to or read from an optical disc having an increased recording density, and which can support an optical disc having the current format.

    摘要： The requested data is read from a DVD disk by interruption in ST46. Then, the ID information for indicating the leading end of the data, and the result of the identification by use of the EDC for indicating whether or not the data is correct are stored in ST47. When the disk is identified as a DVD-video disk and the flag is set in ST 48, and also when the number of times N of retries is identified as being larger than NR in ST50 and the read data is not identified as control data in ST51, data transmission is performed. When no flag is set, the disk identification is performed based on whether or not the data at a predetermined position on the logical format has predetermined data in ST49. When it is identified that an error has been detected in ST52 and also when the number of times N of retries becomes larger than NS in ST53, the occurrence of an error is announced.

    摘要： The amount of light reflected from a disk is detected, and it is determined according to the amount of reflected light whether the disk is a recordable disk or a rewritable disk. The disk is controlled according to the result of determination such that it is rotated at a constant angular velocity (CAV) or at a constant linear velocity (CLV) and recording is executed. Further, rotation driving control of the disk is selected according to factors other than the type of the disk, such as according to whether random recording is allowed or not, according to a recording state in the disk, according to whether an alternative area is provided or not, according to a recording start position, or according to whether initialization is required or not. CLV control or CAV control is appropriately selected for a disk at recording to suppress a reduction in accessibility and a reduction in data transmission rate.
