ABSTRACT:
An apparatus for monitoring and preventing unauthorized copying of digital data. A recording device records digital data on a first storage medium which has been read from a second storage medium. A computer connected to said recording device and the reading device is programmed to execute premastering instructions to enable reading of data from a second storage medium in order to record the data on the first storage medium. The computer further includes instructions for inhibiting copying of the data when said data is subject to copyright by detecting a notice of copyright in the data and inhibiting the premastering instructions from reading the data which includes the copyright notice thereby preventing recording of the data on the first medium.
