Abstract
The present invention provides a disc player comprising one or more light sources that project a pulsing light onto the upper portion of a disc being played by the disc player. The pulse frequency, pulse length, pulse period, pulse interval, pulse color, pulse intensity or a combination thereof of the light source can be synchronized with the rotation of the spindle 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.
