    • PROBLEM TO BE SOLVED: To increase a recording speed and to make uniform the number of rewriting times in each area of a recording medium when the recording unit of an optical disk and the management unit of a file system are different from each other. SOLUTION: A plurality of files B, C, M and P are cached in a memory by the management units of a file system. The cached files are discharged by a minimum recording unit (RUB) of a disk and recorded in the RUB 215 of the disk. After the recording, the RUB 215 is closed to move a write point to a next RUB 216. A part of the file 214 exceeding the size of the RUB among the cached files is discharged from the memory by the RUB and recorded in the RUB 216. After the recording, the RUB 216 of the recording is closed to move a write point to a next RUB 217. Since data modify writing is unnecessary, fast recording is carried out, and the number of rewriting times for each RUB is made uniform. COPYRIGHT: (C)2007,JPO&INPIT
    • 要解决的问题:当光盘的记录单元和文件系统的管理单元彼此不同时,提高记录速度并使记录介质的每个区域中的重写次数均匀化 。 解决方案:文件系统的管理单元将多个文件B,C,M和P缓存在存储器中。 缓存的文件由磁盘的最小记录单元(RUB)放电并记录在磁盘的RUB 215中。 在记录之后,关闭RUB 215以将写入点移动到下一个RUB 216.超过缓存文件中的RUB的大小的文件214的一部分由RUB从存储器释放并记录在RUB 216中 在记录之后,记录的RUB 216被关闭以将写入点移动到下一个RUB 217.由于数据修改写入是不必要的,因此执行快速记录,并且使每个RUB的重写次数均匀。 版权所有(C)2007,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide an optical disk reproducing device which has low power consumption and can obtain sufficient reproducing performance. SOLUTION: After waveform of reproducing RF signals 3 detected from an optical disk medium 1 is shaped, they are converted into digital RF signals 6 using a sampling clock 8 of a period twice a channel clock. Then, after offset fluctuations in high frequency region are compensated through a first offset compensation circuit 9 and adaptive equalization is carried out with a digital adapting equalizer 23 through a second offset compensation circuit 27, offset components remained in the first offset compensation circuit 9 are compensated and digital binarization signals 37 are demodulated. This reduces power consumption while maintaining highly efficient reproducing performance, even when high speed reproducing is performed and the asymmetry depending on recording quality is large.

    • 要解决的问题:提供一种具有低功耗并且可以获得足够的再现性能的光盘再现装置。 解决方案:在从光盘介质1检测到的再现RF信号3的波形成形之后,使用采样时钟8将两个通道时钟的采样时钟8转换成数字RF信号6。 然后,在通过第一偏移补偿电路9补偿高频区域的偏移波动之后,通过第二偏移补偿电路27通过数字适配均衡器23执行自适应均衡,残留在第一偏移补偿电路9中的偏移分量被补偿 解调数字二值化信号37。 这降低了功耗,同时保持高效率的再现性能,即使当执行高速再现并且取决于记录质量的不对称性大时也是如此。 版权所有(C)2006,JPO&NCIPI
