摘要： An information reproducing apparatus according to the present invention is capable of reproducing an information storage medium storing BCA information recorded in a first area and RF information recorded in a second area on an outer side of the first area. The information reproducing apparatus includes an optical pickup to radiate laser light onto the first and second areas and detect reflected light thereof; a reproducing system unit to reproduce an RF signal and a BCA signal on the basis of the reflected light; and a focus control unit to control focusing by setting a focus position to a signal layer of the optical disc when the RF signal is to be reproduced and control defocusing by displacing the focus position from the signal layer when the BCA signal is to be reproduced, thereby equivalently suppressing a high-frequency component of the BCA signal.

摘要： A plurality of defect management areas (DMA set groups 1 to N) are used in a ring form in such a manner that defect management information of the DMA replaces and is recorded in the next spare area while the DMA is supposed to be still sufficiently rewritable (e.g., currently used DMA sets #1-1 to #4-1 are replaced with the next DMA sets #1-2 to #4-2), and a process returns to a first defect management area again at a time when transition of the defect management information ends up to a last spare area (DMA sets #1-N to #4-N).
摘要翻译：以环形式使用多个缺陷管理区域（DMA集组1至N），使得DMA的缺陷管理信息替换并记录在下一个备用区域中，同时DMA应该仍然是可充分重写的（例如，当前使用的DMA集＃1-1至＃4-1被替换为下一个DMA集＃1-2至＃4-2），并且处理在转换时再次返回到第一缺陷管理区的缺陷管理信息结束到最后一个备用区（DMA集＃1至N＃4 -N）。

摘要： An information storage medium has a system lead-in area and a data lead-in area, and an area identifying circuit identifies whether a light beam irradiation area of an optical pickup head is at the system lead-in area or at the data lead-in area based on a reproduction signal provided from the optical pickup head. The area identifying circuit identifies the respective areas by using the number of zero crossings obtained from a signal, for example, into which the reproduction signal is binarized. An information reproducing circuit reproduces information from the reproduction signal based on the identified result by the area identifying circuit.

摘要： Data on multiple stories or scenes are recorded on a recording medium so as to reduce the physical distance moved by a pickup at playback time and to suppress breaks or disturbances in reproduced video. A multi-scene program having a plurality of optionally selectable branch stories B0, B1, B2, B3, etc., is recorded between a branch point X and a connection point Y. The preceding main story of a video program, made up of video, sound, text and the like, branches off at branch point X to the branch stories, and at connection point Y connects to the succeeding main story in the video program. The recorded state between the branch point X and the connection point Y is such that the branch stories are each divided into multiple cells and the cells of the respective branch stories are recorded time-division multiplexed.
