摘要： An optical disc capable of repeated recording, such as a DVD−RW, is applicable. An information recording and reproducing apparatus starts recording by making a sync pattern of recording data correspond to a recording reference position determined by an LPP formed on the disc at the time of recording new data on the disc. Afterward, the apparatus continues the recording by gradually shifting a position of the sync pattern of the recording data with respect to the recording reference position, and performs the recording with a shift quantity fixed to the predetermined shift quantity when the shift quantity thereof reaches a quantity equal to or larger than a predetermined quantity. Thereby, at a rewriting portion on the optical disc, the shift between recorded data and a recording start position of recording data for rewriting can be small, and establishing synchronization at the time of reproducing or rewriting can be stably performed.

摘要翻译： 能够重复记录的光盘，例如DVD-RW。 信息记录和再现设备通过使记录数据的同步模式对应于在盘上记录新数据时由形成在盘上的LPP确定的记录参考位置来开始记录。 之后，装置通过逐渐地移动记录数据的同步图形的位置而相对于记录基准位置继续记录，并且当其移动量达到数量时，以固定为预定移位量的移位量进行记录 等于或大于预定量。 因此，在光盘上的重写部分，记录数据与用于重写的记录数据的记录开始位置之间的偏移可以很小，并且可以稳定地执行再现或重写时的建立同步。

摘要： A recording medium includes pairs of groove tracks and land tracks having periodically formed bent portion provided side by side on a substrate, a plurality of land prepits previously formed on the land tracks and carrying information about the groove tracks, and a recording layer formed on at least the groove tracks and the land tracks. The land prepits have a radius of mean curvature smaller than a radius of mean curvature of sides of the groove tracks in land-prepit absent regions of the land prepits and are defined by curved surfaces continuously extending from the sides of the groove tracks. Those sides of the groove tracks which face the continuous curved surfaces of the land prepits are curved surfaces that stricture the groove tracks. The depth of the land prepit is larger than that of the groove track.
