摘要： To reduce influence of errors on the outer periphery side of a multi-layer recording disc, a first shifted middle area is assured at a predetermined position nearer to the inner periphery side than the last position of layer on the outer periphery side of a single-sided, multi-layer recording disc, and a second shifted middle area is assured at the position of layer that opposes the shifted middle area assured on layer. A recording layer extending from layer to layer may be shifted in the first and second shifted middle areas, and an area in which errors relatively readily occur on the outer periphery side of the first and second shifted middle areas may not be used.

摘要： This invention relates to a recording/reproduction system having a function of recording/reproducing video information with a GOP structure in the MPEG2 scheme on/from a disk. In this system, when a cut position designated by the user on the reproduction frame is set within the GOP, start picture data in the latter half of video data using the cut position as the reference position is set to I picture data. That is, when the picture data is of the B type, the CPU controls an encoder/decoder to change the picture data to I picture data. Accordingly, the latter half can be generated as reproducible video data.

摘要： An information storage medium is designed to assure stable continuous recording without adverse effect, even when many defective areas are present on the information storage medium. To record information onto the information storage medium, a file unit is defined as a first unit. A contiguous data area unit to be treated as a continuous recording area is defined as a second unit. Furthermore, recording is done in the contiguous data area units and a collection of the contiguous data area units is organized into the file unit. In addition, an information recording place is provided in such a manner that the contiguous data area unit is so set that it extends over the recording area of another file already recorded on the information storage medium and a defective area on the information storage medium.

摘要： In a data recording and reproducing apparatus which records and reproduces a record medium in which at least two kinds of data having different data types can be recorded, data is read out from the record medium, and a digital watermark is detected from the data read out. The kind of data is determined depending upon whether the digital watermark is detected, and it is determined whether retry processing at the time of reading-out the data and verifying processing at the time of writing should be executed. The retry processing or the verifying processing is executed only for the data which is determined that the retry processing or the verifying processing should be executed. Therefore, in the case of data whose reading-out continuity is more important than reliability, the retry processing is omitted, so that time required for reading-out processing can be shortened. In the case of data whose recording continuity is more important than reliability, the verifying processing is omitted, so that time required for writing processing can be shortened.

摘要： Music related information is transmitted to a user over a mobile telephone network, and the user can select a desired music program based on a display listing transmitted from the base station. The transmission speed of the transmitted data is checked and if the transmission speed is below a predetermined rate a data stream is generated every predetermined time with a portion of the music data being left out, so that a listenable audio signal can be produced based on this generated data stream.
