>electrical tape, crackers have discovered.

>The Blue Peter-style hack, which was first unearthed by a reader of
>chip.de works by covering up the outer ring of a copyright protected
audio disc.

>On copy protected discs this outer track is corrupted, which prevents

>regular CD players.

>Simply covering up the outer track disables the protection, allowing a
