Abstract:
1. A method of copying a copy protected optical disc, the method comprising the steps of: reading data from an optical disc at a selected level which differs from the user data level, and writing the data read from said selected level to an optical disc to create a usable copy of a copy protected optical disc, wherein the data levels at least comprise, from highest to lowest, the user data level, a data frame level, an error corrected level, an interleaved level, and an encoded data level, and wherein the data is provided from the optical disc at a level above the encoded data level but below the user data level, and writing the provided data to an optical disc, commencing at a data level which corresponds to the data level from which the data has been provided and continuing through the data levels to produce encoded data in the form of a bit stream, which bit stream is written to the optical disc.
