    • A high-density optical disc such as BD-RE (Blu-ray Disc Rewritable) or BD-ROM, and a recording/reproducing method thereof are disclosed. Diverse additional information such as disc reflectivity information, disc layer information or disc type information is efficiently recorded in a particular information field included in a data unit recorded on the burst cutting area of a high-density optical disc or a particular 1-byte address field included in an address unit recorded on the high-density optical disc so that it can be read when the high-density optical disc is loaded in an optical disc apparatus or when a data recording or reproducing operation for the high-density optical disc is carried out. Accordingly, it is possible to achieve optimal optical power control and automatic gain control or identification of a current position, while enabling a normal data recording or reproducing operation corresponding to the type of the optical disc.
    • 公开了诸如BD-RE(蓝光盘可重写)或BD-ROM的高密度光盘及其记录/再现方法。 多个附加信息,例如光盘反射率信息,光盘层信息或光盘类型信息被有效地记录在记录在高密度光盘的突发切割区域或特定的1字节地址字段上的数据单元中的特定信息字段中 包含在记录在高密度光盘上的地址单元中,使得当高密度光盘装载在光盘装置中时或当携带高密度光盘的数据记录或再现操作时可以读取它 出来 因此,可以实现最佳光功率控制和自动增益控制或当前位置的识别,同时能够进行与光盘类型相对应的正常数据记录或再现操作。
