摘要： A read only disc according to the present invention has a spiral recording track formed on the surface thereof. The recording track includes a plurality of record unit blocks formed continuously by an optical recording method, wherein each record unit block includes a dubbing permitted area and a dubbing inhibited area. Digital audio information having data compressed is recorded in the dubbing permitted area. On the other hand, display data associated with the digital audio information is recorded in the dubbing inhibited area. Thus, digital dubbing of digital audio information can be carried out and dubbing of display data is prevented to ensure dominance of the read only disc as a master software.
摘要翻译： 根据本发明的只读盘具有形成在其表面上的螺旋记录轨迹。 记录轨道包括通过光学记录方法连续形成的多个记录单元块，其中每个记录单元块包括转录允许区域和复制禁止区域。 具有压缩数据的数字音频信息被记录在转录允许区域中。 另一方面，与数字音频信息相关联的显示数据被记录在转录禁止区域中。 因此，可以执行数字音频信息的数字翻录，并且防止显示数据的转录，以确保只读盘作为主软件的优势。
