    • An optical disk structure and optical disk recorder which enables data to be re-written onto the recording layer of the optical disk. A clock reference structure is permanently formed along servo tracks of the optical disk. An optical transducer is coupled to the clock reference structure and generates a clock reference signal simultaneously with writing new data onto the recording layer of the optical disk. The data is written as data marks along the servo tracks. Each of the data marks includes edges. The edges of the data marks are recorded in synchronization with a write clock. The write clock is phase-locked with the clock reference signal. Therefore, the edges of the data marks are aligned with the clock reference structure with sub-bit accuracy. Standard DVD-ROM disk readers are not able to detect the high spatial frequency of the clock reference structure. Therefore, the optical disk structure and optical disk recorder of this invention allow production of re-writable optical disks which can be read by standard DVD-ROM disk readers.
    • 一种光盘结构和光盘记录器，其使得能够将数据重写到光盘的记录层上。 时钟参考结构沿着光盘的伺服轨道永久地形成。 光学传感器耦合到时钟参考结构，并且在将新数据写入光盘的记录层的同时产生时钟参考信号。 数据沿伺服轨迹写入数据标记。 每个数据标记包括边。 数据标记的边缘与写时钟同步记录。 写时钟与时钟参考信号锁相。 因此，数据标记的边缘与子位精度与时钟参考结构对齐。 标准DVD-ROM光盘读取器不能检测到时钟参考结构的高空间频率。 因此，本发明的光盘结构和光盘记录器允许生产可由标准DVD-ROM盘读取器读取的可重写光盘。
