摘要： An optical disk physical has a recording region divided into zones, each zone including physical tracks adjacent to each other. An integer number of sectors are provided in each physical track. The angular recording density is higher in the more outward zones such that the linear recording density is substantially constant throughout the recording region, and logical tracks are formed of a predetermined number of sectors. independent of the physical tracks. The conversion between the logical track and sector addresses read from the disk and the linear logical addresses supplied from a host device is easy. The addresses written in headers of the sectors in the logical track in which data are actually recorded, including substitute sectors used in place of defect sectors, are preferably consecutive to further facilitate the conversion between the logical track and sector addresses read from the disk and the linear logical addresses supplied from the host device. Each of the zones can be set to serve as any of the different types of recording area, independently of other zones.

摘要： A system and method summarizes multimedia stored in a compressed multimedia file partitioned into a sequence of segments, where the content of the multimedia is, for example, video signals, audio signals, text, and binary data. An associated metadata file includes index information and an importance level for each segment. The importance information is continuous over as closed interval. An importance level threshold is selected in the closed interval, and only segments of the multimedia having a particular importance level greater than the importance level threshold are reproduced. The importance level can also be determined for fixed-length windows of multiple segments, or a sliding window. Furthermore, the importance level can be weighted by a factor, such as the audio volume.

摘要： An optical disk has two sides for recording data and at least one recording area for each side. Each recording area is associated with an attribute which designates whether the corresponding recording area is an area which permits rewriting or an area which does not permit rewriting. Data representing the attribute for the at least one recording area of each side is recorded in a structure management table provided in a predetermined part of the disk of each side. The two sides of the disk have different attributes.

摘要： A method of retrieving recorded information from an optical recording medium and writing information in an optical recording medium. The method is applicable to optical recording media having different track pitches. Before reading information or recording information, a laser beam is employed to read from a control track area of an optical recording medium track pitch information including the track pitch of the medium. Then, based upon the track pitch read, the shape of the spot of the laser beam incident on the optical recording medium is adjusted so that it conforms to the track pitch determined by reading the information from the control track area.
