摘要： An optical or magneto-optical disk storage which automatically adjusts a recording/reproducing level of a number of kinds of optical or magneto-optical disks having different recording/reproducing levels to an optimum recording/reproducing level. The optical or magneto-optical disk storage has an attenuator which applies a predetermined attenuation amount to a reproduced signal reproduced from an optical or magneto-optical disk so as to attenuate the reproduced signal, or intensity adjusting means for adjusting the intensity of a laser beam used for recording and/or reproducing. The optical or magneto-optical disk storage detects an amplitude of the reproduced signal and feed-back-controls the attenuation amount or intensity of the laser beam in accordance with the detected amplitude.

摘要： Methods and apparatuses are disclosed for improving accuracy of recording and reproducing information onto and from a magneto-optic recording information medium. In the first method, a width of a mark formed by a relatively low intensity light beam between two kinds of light beam intensities used for recording information is made larger than a sum of a track land width and the maximum track offset of the light beam, thereby the mark formed by the relatively low intensity light beam covers the track land portion in its full width. In the first apparatus, a reflected light beam from the magneto-optic recording information medium is split into a reflected beam for information reproducing and a reflected beam for tracking and focusing servos at the reproducing, thereby the apparatus can remove part being affected by the track groove portion from the reflected light beam for information reproducing. In the second method and apparatus, an intensity ratio of the two kinds of intensities of light beams used for information recording is controlled in such a manner that a mark width formed by the relative low intensity light beam is wider than a mark width formed by the relative high intensity light beam.

摘要： In an optical disk storage, the seek of an optical head is controlled so that the number of seek times cannot exceed a threshold number of times in a predetermined period or an accumulated seek period cannot exceed a threshold period in a predetermined period. Therefore, a wasteful power consumption and a rise in the internal temperature associated with the seek activity can be effectively prevented.

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： 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。 每个区域可以设置为独立于其他区域，用作任何不同类型的记录区域。
