Information storage medium capable of restricting number of times that data can be reproduced, method and apparatus for recording data on the information storage medium, and method and apparatus for reproducing data from the information storage medium
摘要:
Provided are an information storage medium from which a total number of times that data can be reproduced is limited, a method and apparatus for recording data on the information storage medium, and a method and apparatus for reproducing data from the information storage medium. The information storage medium includes a data zone storing user data, and a control information zone storing control information regarding controlling a number of times that the user data can be reproduced. Accordingly, a content provider who provides content such as a movie can create various types of business models by recording content on the aforementioned information storage medium, and selling it at a cheaper price. Further, control information is recorded on the information storage medium or a write once zone of the information storage medium before recording content or user data thereon, thereby preventing the control information from being changed or deleted.
