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。

摘要： In recording data on a rewritable optical disk with a mark edge recording method, the occurrence of edge shift is compensated for. As a first power of a laser beam is greater than a second power, start and termination ends of each mark are produced by irradiation of the first power and a remaining intermediate portion of the mark is produced by irradiating the first and second powers alternately at equal intervals of a predetermined duration which is shorter than a period of a clock pulse. Also, the start and termination ends of the mark are specifically dislocated corresponding to a length of the mark and lengths of two neighbor spaces before and after the mark.

摘要： A video disc is produced from a master video disc which has recorded therein a video signal including a synchronous signals occurring periodically and divided into plural channels by the cycle of the synchronous signals. The plural channel signals are recorded on a group of plural tracks, respectively. In the case of reproducing the video disc, the plural channel signals are reproduced from the group of plural tracks, respectively. Synchronous signals are detected from the reproduced signals. The reproduced channel signals in a period of the synchronous signal are stored in plural memories based on the synchronous signals detected. The stored plural channel signals are continuously reproduced by successively reading from the memories of channels by switching at synchronous intervals. The signal bandwidth of the channels becomes 1/n of the original video signal by recording and reproducing the video signal by dividing it into plural channels(n channels) in such manner. Therefore, even when the shortest recording wavelength is the same, the linear velocity is reduced by 1/n.
摘要翻译：从主视频盘产生视频盘，其中记录有包含周期性发生的同步信号的视频信号，并通过同步信号的周期被划分为多个信道。多个信道信号分别记录在一组多个磁道上。在再现视频盘的情况下，分别从多个磁道组再现多个声道信号。从再现信号中检测同步信号。基于检测到的同步信号，将同步信号的周期中的再生信道信号存储在多个存储器中。所存储的多个信道信号通过以同步间隔切换从信道的存储器连续地读出来连续再现。通过以这种方式将视频信号分成多个信道（n个信道）来记录和再现视频信号，信道的信号带宽变为原始视频信号的1 / n。因此，即使最短记录波长相同，线速度也减少1 / n。

摘要： An optical disc drive apparatus (100) of the present invention rotates an optical disc (1) at a predetermined rotation speed using a motor (2). An optical pickup (3) irradiates the optical disc (1) with a laser beam (5) emitted from an internal semiconductor laser (4) included therein, and obtains a reproduction signal (7) based on a laser beam reflected from the optical disc (1). A laser driving unit (8) controls a driving current (9) of the semiconductor laser (4) to a predetermined level, and superimposes a high-frequency current (11) having a predetermined level on the driving current (9). In a high-speed reproduction mode, a control unit (12) sets the rotation speed of the optical disc (1) higher, the power of the laser beam (5) irradiating the optical disc (1) higher, and the level of the high-frequency current (11) lower than in a normal reproduction mode.

摘要： A method for writing a signal on an optical disk is disclosed. The optical disk comprises a track groove on a recording surface thereof, on which information is recorded along the track groove on a block-by-block basis each said block having a predetermined length and where an identification mark indicating the beginning of each said block, has been formed on the track groove. Writing is started before the identification mark, located at the beginning of at least one block on which the signal should be written, is reached and writing is ended after the identification mark located at the end of the at least one block on which the signal should be written has been passed.
