摘要： When recording and reproduction are performed at the same time, if a system controller detects that an amount of data accumulated in a buffer memory exceeds a predetermined value, the system controller stops data reading from an optical disk temporarily and records data accumulated in the buffer memory continuously to the optical disk. Then, an image is prevented from becoming abnormal when a reproduction position catches up to a recording position. Further, a system controller monitors a zone in an optical disk, to which recording is performed and controls a motor at an appropriate revolution number for the recording to the zone. Further, reproduction is performed by maintaining the revolution number. Then, even if the recording position and the reproduction position belong to different zones in a recording medium, a transition time from recording to reproduction is prevented from becoming long.

摘要： The operating and other procedures of an optical disk application system of the type for which a network is used are simplified. Optical disks have auxiliary data recording areas, where different IDs for individual disks, and/or cipher keys and/or decoding keys for ciphers are recorded in advance in a factory. By using the IDs to release the soft ciphers, using the cipher keys when sending the ciphers, and using the decoding keys when receiving the ciphers, user authorization procedures are simplified.

摘要： An optical disk and a method for storing write-once information usable for preventing the illegal copies. The optical disk comprises a disk substrate, and a recording layer having a magnetic film disposed on the disk substrate. The optical disk stores write-once information formed by first recording areas and second recording areas and the write-once information being different for each disk. The second recording areas are formed as a plurality of stripe-shaped marks that are oblong in a radial direction of the disk by irradiating laser light based on a modulation signal of the write-once information in the pre-determined portion of the recording layer, in a manner that a magnetic anisotropy in a direction perpendicular to a surface of the second recording areas is smaller than a magnetic anisotropy in a direction perpendicular to a surface of the first recording areas.

摘要： In an optical disc, an ID field contains a plurality of address information, and is preliminarily recorded in convex and concave signals, and is composed of two sets offset by about 1/2 track pitch toward the internal or external track direction adjacent to the guide track, an information recording field is composed of grooves and lands oscillating at a single frequency in the radial direction, and the grooves and lands alternate in every revolution of the guide track. When w bits of information are included in one period of oscillation, an information unrecorded field between the ID field and information recording field is arranged to have a length of w/10 bits or more and/or w bits or less, and therefore, when recording continuous information data such as video data, it is possible to record continuously by generating a clock securely from the oscillating signal, and moreover, the format efficiency is improved, so that a format of a larger capacity is achieved.

摘要： An information recording apparatus for continuously recording information without losing any information even if the apparatus temporarily falls into a recording-disable state owing to the shock externally applied, etc. is provided. A disability detector for detecting the recording-disable state is provided in the information recording apparatus, thereby interrupting the recording operation and the reading operation from the buffer memory under the recording-disable state, and making a coding rate reduction controller instruct a coder to temporarily reduce the coding rate of the input information. A remaining capacity detector is provided for monitoring the remaining capacity in the buffer memory and instructing the coder to temporarily reduce the coding rate of the input information when the remaining capacity becomes a predetermined value or less. As a result, the reduction in the remaining capacity of the buffer memory under the recording-disable state is prevented. When the overflow of the buffer memory is detected, the information after the generation of the overflow is controlled to be overwritten on a part of the data already written into the buffer memory. The variation history of the case where the recording data amount is varied by the coder because of the variation in the coding rate of the input information or the overwriting operation in the buffer memory is controlled to be recorded on the disk as rate variation management information. By dividing the recording area on a disk-shaped information recording medium into an inner circumference and an outer circumference and recording on the outer circumference after the return from the recording-disable state, the recording transfer rate after the return becomes higher.
摘要翻译：提供一种用于连续地记录信息而不丢失任何信息的信息记录装置，即使该装置由于外部施加的冲击而暂时处于记录禁止状态等。在信息记录装置中提供用于检测记录禁止状态的残障检测器，从而在记录禁止状态下从缓冲存储器中断记录操作和读取操作，并使编码率降低控制器指示编码器临时降低输入信息的编码率。提供剩余容量检测器，用于监视缓冲存储器中的剩余容量，并指示编码器在剩余容量变为预定值或更小时临时降低输入信息的编码率。结果，防止在记录禁止状态下缓冲存储器的剩余容量的减少。当检测到缓冲存储器的溢出时，控制溢出生成之后的信息，以覆盖已经写入缓冲存储器的数据的一部分。由于输入信息的编码率或缓冲存储器中的重写操作的变化而由编码器改变记录数据量的情况的变化历史被控制为以速率变化管理信息记录在盘上。通过将盘状信息记录介质上的记录区域划分成内周和外圆，并且在从记录禁止状态返回之后在外圆周上记录，返回之后的记录传送速率变高。
