    • PURPOSE: An optical disk recording method and a device thereof are provided to set plural buffer pointers to at least more than one group, in order to reduce the number of retrieval times, thereby improving a recording performance while reducing a retrieval time. CONSTITUTION: A system receives/recognizes a recording command of an optical disk driver from an outer host(1S), and confirms whether an LBA(Logical Block Address) of received data is continuous(2S), then adds the data to the first group(3S). If the LBA is not continuous, the system confirms whether the group is an existing group(4S), and generates or adds a new group(8S). The system confirms whether the second group is continuous(5S), and adds the data to the second group(6S). If the second group is not continuous, the system confirms whether another existing group is produced(7S), and confirms whether a buffer is filled with data of the first and second groups(9S). If so, the sequentially retrieves the groups(10S), and sequentially records/reproduces the data by group(11S).
    • 目的:提供光盘记录方法及其装置,以将多个缓冲指针设置到至少一个组,以便减少检索次数,从而在减少检索时间的同时提高记录性能。 构成:系统从外部主机(1S)接收/识别光盘驱动器的记录命令,并确认接收到的数据的LBA(逻辑块地址)是否连续(2S),然后将数据添加到第一组 (3S)。 如果LBA不连续,系统将确认组是否是现有组(4S),并生成或添加新组(8S)。 系统确认第二组是否连续(5S),并将数据添加到第二组(6S)。 如果第二组不连续,则系统确认是否生成另一个现有组(7S),并确认缓冲区是否填充有第一组和第二组(9S)的数据。 如果是,则顺序地检索组(10S),并且按组(11S)顺序地记录/再现数据。
