| 摘要 |
<p>The invention refers to an optical storage medium from which information can be read out and/or into which information can be recorded with a light beam (6), said optical storage medium comprising one or more base members (1) bearing on the side of the base members (1) on which the light beam (6) is incident, one or more information storage layers (3) and at least one light-transmissive cover film (5) wherein said cover films (5) are bonded to each other, to the surface (2) of the base members (1) on which the light beam (6) is incident and/or to one or more information storage layers (3) by means of one or more light-transmissive pressure-sensitive adhesive layers (4), and wherein said cover films (5) are essentially optically isotropic at least at the wavelength or wavelength spectrum, respectively, of said light beam (6).</p> |
