摘要： When optical disk defects are arranged by using non-defective areas in place of defective areas, different criteria are used for detecting the defects, depending on the type of data recorded on the disk. For example, to avoid interruptions of real-time recording, less strict criteria are used when audio or video data is recorded than when computer data is recorded. The criteria themselves may also be recorded on the disk.

摘要： An optical disc using a single-spiral land and groove track format and an address signal enabling simple sector address management and format compatibility with read-only optical disc media is disclosed. Four physical address areas PID1-PID4 are recorded to a header area such that PID1 and PID2 are offset one-half track pitch toward the outside circumference of the disc from the groove track center, and PID3 and PID4 are offset one-half track pitch toward the inside circumference of the disc from the groove track center, and the header area is shared by groove track sectors and land track sectors. A groove track sector address is written to PID3 and PID4, and the sector address of the land track sector adjacent on the outside circumference side of that groove sector is written to PID1 and PID2. The address of each sector increases 1 in the same sequence as the sectors are formed in the recording spiral.

摘要： In a system for visualizing a stereoscopic image by displaying separate video images for the left and right eyes, sub-picture data (GRD) is created for the left eye and displayed superimposed on left-eye video data (VDD) as a left-eye sub-picture without change. The right-eye sub-picture (106) is displayed by shifting the horizontal positions at which the sub-picture data created for the left eye is displayed by prescribed widths. For example, the sub picture may include a plurality of objects (GRD-1, GRD-2, . . . , GRD-N); shift widths (108, 110) of the horizontal positions of the left and right ends of the objects are individually set and stored in the sub-picture data for displaying the objects for the right eye. A sub-picture superimposed on a stereoscopic video image can thereby be rendered in the depth direction, and the data size of the sub-picture and the amount of computation required for its display can be reduced.
