<P>PROBLEM TO BE SOLVED: To provide label recording in which deterioration of characters and an image printed a label surface is reduced and which can prevent alteration by differentiating other companies and other persons. <P>SOLUTION: A laser beam of an optical information recording and playback head physically forms wavelength distribution optical elements on an optical molding resin label surface covered with a cover layer to thereby perform label printing in which the colors of characters and an image of a label are changed into seven colors according to angles at which the label surface is looked at, achieving an individual design. Moreover, since the wavelength distribution optical elements are physically formed, alteration prevention is achieved without damaging the individual design. <P>COPYRIGHT: (C)2008,JPO&INPIT |
