摘要： When optical disk defects are managed by using non-defective areas in place of defective areas, different criteria are used for detecting the defects, depending on the type of data recorded on the disk. For example, to avoid interruptions of real-time recording, less strict criteria are used when audio or video data is recorded than when computer data is recorded. The criteria themselves may also be recorded on the disk.

摘要： An optical disk according to the present invention has data recording tracks of lands and grooves. Each of the data recording tracks has a length corresponding to a revolution of the disk and includes a plurality of track sectors. The data recording tracks of lands and grooves are connected alternately to each other so as to form a continuous data recording spiral. Each of the track sectors has a preformatted identification signal part for representing sector address data and has a data recording part for recording data. The identification signal part has the first address data region and the second address region. The first address data region and the second address data region are shifted by the same predetermined distance from the center of a groove track oppositely in the radial direction of the disk. The first address data region is set to represent the address of a groove track sector, and the second address data region is set to represent the address of a land track sector adjacent to the groove track sector.

摘要： An optical disc using a single-spiral land and groove track format and an address signal enabling simple sector address management and format compatibility with read-only optical disc media is disclosed. Four physical address areas PID1-PID4 are recorded to a header area such that PID1 and PID2 are offset one-half track pitch toward the outside circumference of the disc from the groove track center, and PID3 and PID4 are offset one-half track pitch toward the inside circumference of the disc from the groove track center, and the header area is shared by groove track sectors and land track sectors. A groove track sector address is written to PID3 and PID4, and the sector address of the land track sector adjacent on the outside circumference side of that groove sector is written to PID1 and PID2. The address of each sector increases 1 in the same sequence as the sectors are formed in the recording spiral.

摘要： An optical disk physical has a recording region divided into zones, each zone including physical tracks adjacent to each other. An integer number of sectors are provided in each physical track. The angular recording density is higher in the more outward zones such that the linear recording density is substantially constant throughout the recording region, and logical tracks are formed of a predetermined number of sectors, independent of the physical tracks. The conversion between the logical track and sector addresses read from the disk and the linear logical addresses supplied from a host device is easy. The addresses written in headers of the sectors in the logical track in which data are actually recorded, including substitute sectors used in place of defect sectors, are preferably consecutive to further facilitate the conversion between the logical track and sector addresses read from the disk and the linear logical addresses supplied from the host device. Each of the zones can be set to serve as any of the different types of recording area, independently of other zones.

摘要翻译： 光盘物理上具有划分成区域的记录区域，每个区域包括彼此相邻的物理轨道。 在每个物理轨道中提供整数个扇区。 在更向外的区域中，角度记录密度更高，使得整个记录区域的线性记录密度基本恒定，并且逻辑磁道由预定数量的扇区形成，与物理轨道无关。 从磁盘读取的逻辑磁道和扇区地址与从主机设备提供的线性逻辑地址之间的转换很容易。 写入数据实际记录的逻辑磁道中的扇区头部的地址，包括用于代替缺陷扇区的替代扇区，优选地是连续的，以进一步促进从盘读取的逻辑磁道和扇区地址之间的转换 从主机设备提供的线性逻辑地址。 每个区域都可以设置为独立于其他区域的任何类型的记录区域。
