<p>The present invention relates to a Digital Rights Management (DRM) method using bad patterns, a method of recording/playing digital contents using the DRM method, a digital contents storage medium for the methods, and a computer readable recording medium for storing programs for implementing the methods. The DRM method of the present invention includes the steps of examining unit area-based bad patterns of a memory device constituting a digital contents storage medium, and determining a bad pattern extraction area, recording an area code value of the determined bad pattern extraction area in a table select code field of a card ID, examining an area corresponding to the area code value recorded in the table select code field, and configuring a bad pattern DRM table based on information about the bad patterns, and generating a bad pattern encryption key based on the bad pattern information.</p> |
