Abstract
An optical recording medium is equipped with a light transmitting layer to have visual effects. Patterns with different visual effects can be printed on the upper and low surfaces of the light transmitting layer. Alternatively, visual effects can be presented by directing light out of an upper light grating from a low printing layer. The optical recording medium can not only record information but also present visual effects.
