ABSTRACT:
The present invention provides a disc player comprising one or more light sources that project a constant or pulsing light onto the upper portion of a disc being played by the disc player. If a constant light source is used, the a pulsing viewing port for the disc receptacle of the disc player is employed. The pulse frequency, pulse length, pulse period, pulse interval, pulse color, pulse intensity or a combination thereof of the light source or the pulse frequency, pulse length, pulse period, pulse interval, or light transmissivity of the one or more viewing ports can be synchronized with the rotation of the spindle or platen in the disc player, with the optical data stored, or with the rotation of an image precursor on the disc. When the disc is viewed through a viewing port while the disc is being played, a two-dimensional or three-dimensional discrete image is formed by the persistence of vision. The disc player can also include an anti-piracy system to prevent unauthorized playing of digital/optical disc content. The anti-piracy system includes a verification system and access control data. When permission granting information is obtained from the disc, the verification system compares it to the access control data and either allows or disallows the disc player to play the disc.
