摘要： An optical disk includes a land and a groove. On this optical disk, data is recorded on both the land and the groove. A distance between the center of the land and the center of the groove adjacent to the land is 0.28 µm or more. The optical disk has a data efficiency of 80% or more. Thus, an optical disk having a storage capacity of 25 GB or more can be provided.

摘要： An optical disc playback apparatus capable of signal processing so that the above-noted new jitter does not appear even when a waveform equalizer is used is provided. A trimmer is inserted before the waveform equalizer, the maximum amplitude in the positive direction of the playback signal waveform and the maximum amplitude in the negative direction are limited so that amplitude in the positive direction and amplitude in the negative direction are substantially equal. Jitter in the playback signal can be improved as a result.
摘要翻译： 一种能够进行信号处理的光盘重放设备，使得即使当使用波形均衡器时也不会出现上述新的抖动。 在波形均衡器之前插入修整器，限制回放信号波形的正方向上的最大幅度和负方向上的最大幅度，使得正方向上的幅度和负方向上的幅度基本相等。 回放信号中的抖动可以因此得到改善。

摘要： An optical disc medium compares a track groove, along which main information is recorded. The track groove is divided into a plurality of blocks. The plurality of blocks each include a plurality of frames. The plurality of frames each include one shape of wobbles indicating sub information, among a plurality of prescribed shapes of wobbles. The plurality of blocks each have address information. The address information is represented by a string of at least one piece of sub information represented by the shape of wobbles of at least one of the plurality of frames.
