<p>Provided are an authentication method that includes connecting an optical disc drive (ODD) for driving a medium and a host device for reproducing contents stored in the medium using an interface. An authentication for reproducing the contents is performed by mutually exchanging data between the host device and the ODD via the authentication area of the ODD for storing the data. Accordingly, the ODD may convert a file from the optical disc, which is in an intrinsic format, into a format that is recognizable by a host device.</p> |
