Abstract
The invention relates to a method of controlling unauthorised copying of data, for example copying of audio data from an original Compact Disc (CD), or copying of audio data files which have been legally purchased over a network system, for example using the Internet. In particular, although not exclusively, the invention relates to a method and apparatus for controlling unauthorised copying of music onto portable solid state memory audio player devices (2), or onto removable solid state memory cards (3) for use with such portable player devices. A data copying and playback system incorporating copy management is also claimed.
