    • In accordance with the invention, upon insertion of an optical disc into a player/recorder system, the system attempts to recognize the disc and read data from the disc. Any error causing failure of a startup procedure will be detected. If a reading error is detected, the disc is rotated by an angle for minimizing the impacts due to the reading error. Then the data is read again from the disc. If a reading error is still detected, the procedure is repeated for a few times to minimize the reading errors. The rotational angle of the disc may be either preset or calculated by the system based on measured eccentricity values. In this way, the combined eccentricity, i.e., the distance from the spiral groove center of the disc to the system’s rotational axis, can be minimized, and the ability of the system to read an optical disc during the startup procedure can be significantly improved.
    • 根据本发明,在将光盘插入播放器/记录器系统中时,系统尝试识别盘并从盘读取数据。 将检测到引起启动过程失败的任何错误。 如果检测到读取错误,则盘旋转一个角度以最小化由于读取错误引起的影响。 然后从光盘再次读取数据。 如果仍然检测到读取错误,则重复该过程几次以最小化读取错误。 盘的旋转角度可以由系统基于测量的偏心度值来预设或计算。 以这种方式,可以将组合的偏心率,即从盘的螺旋槽中心到系统的旋转轴的距离最小化,并且可以显着地提高系统在启动过程期间读取光盘的能力。

    • A system and method for defining rewriteable data storage media defined by ECMA Standard ECMA-272 2 edition (1999) for 120 mm DVD rewriteable disk (DVD-RAM) as a write once data storage media and for storing data thereon. The apparatus consists of a data storage device for reading and writing data on the media, the media, a media type indicator in the media, two write protect flags in the user data area of the media, and programming to examine the two write protect flags prior to a write, erase, or format operation. If both flags match and the media type indicator is write once, the drive is prevented from writing to the user data area if both flags are in the data written state. If both flags do not match after two re-reads, an error message is generated. If both flags are in the data unwritten state, data is written to the user data area and both flags are set to the data written state.
    • 一种用于定义可重写数据存储介质的系统和方法,该可重写数据存储介质由作为一次写入数据存储介质的120mm DVD可重写盘(DVD-RAM)定义的ECMA标准ECMA-272第2版(1999)和用于在其上存储数据。 该装置包括用于在媒体上读取和写入数据的数据存储装置,媒体,媒体中的媒体类型指示符,媒体的用户数据区域中的两个写保护标志,以及用于检查两个写保护标志 在写,擦除或格式化操作之前。 如果两个标志匹配,并且媒体类型指示符写入一次,则如果两个标志都处于数据写入状态,则禁止驱动器写入用户数据区。 如果在两次重新读取后两个标志都不匹配,则会生成错误消息。 如果两个标志都处于数据未写状态,则将数据写入用户数据区,并将两个标志设置为数据写入状态。

    • A method, disc drive, and data handling system for optimizing the data writing/transmitting process are disclosed. The disc drive implemented method involves detecting at a current burst whether data written to a previous wedge is recoverable and making the disc drive's buffer space holding that data available for holding other data when the written data is recoverable. The disc drive implemented method also involves detecting at the current burst whether data to be written to a following wedge will encroach upon data written in adjacent tracks and allowing the data to be written in the following wedge the encroachment is not too severe.
    • 公开了一种用于优化数据写入/发送过​​程的方法,盘驱动器和数据处理系统。 盘驱动器实现的方法涉及在当前突发情况下检测写入前一个楔块的数据是否可恢复,并且当写入数据可恢复时,使得盘驱动器的缓冲空间保持该数据可用于保持其他数据。 磁盘驱动器实现的方法还涉及在当前突发情况下检测要写入后续楔形的数据是否将侵占写在相邻轨道中的数据,并允许以下面的楔形写入数据,侵占不会太严重。
