  • Patent number: 5896255
    Abstract: A disc cartridge and corresponding method/system are provided for limiting the number of copies which may be made of software stored on a magnetic disc. A magnetic field generating member is provided within a magnetic disc cartridge, or embedded within a magneto-optical or magnetic disc, so that after copying of the software from the first disc to a second disc, the magnet is energized so as to create an erasing magnetic or electromagnetic field proximate the first disc in order to erase the copied software therefrom, while an anti-copy signal is copied or otherwise sent along with the software from the first disc to the second disc so as to prevent later copying of the software from the second disc. According to certain other embodiments of this invention, a method/system is provided for erasing software from a disc using the above-discussed cartridge after a user attempting to copy the software enters an incorrect password a predetermined number of consecutive times.
