Abstract
A data recording system and a method of preventing copying data from a recording medium are disclosed. The method comprises an optical recorder receiving modulated bits encoded by EFM/EFM+ (Eight-to-Fourteen Modulation/Eight-to-Fourteen Modulation Plus), the optical recorder converting modulated bits to channel bits, and recording the channel bits to the recording medium. The modulated bits and the channel bits are readable by the optical recorder.
