There is described a recording method of a digital magnetic recording medium for a copyright protection and a variable speed playback when a user records a digital broadcasting program by a digital video cassette recorder (DVCR) or variable speed playback of a rental tape while performing a copyright protection function, a video track of a video tape is separated into a scrambling data region where scrambling data is recorded and a descrambling region where descrambling information for descrambing the scrambling data is recorded to record the video data on the corresponding region. When this method is adopted with a proper copyright protection system, the copyright of the program provider can be protected, and the lowering of the performance is also minimized during the user's variable speed playback of the video tape to which the copyright protection function is adopted, thereby satisfying both the program provider and the user. <IMAGE> |
