摘要:
The present invention relates to DVDs. According to the present invention, the recording layer is at least partially or entirely positioned at a distance T 7 of less than 0.4 mm with respect to the second surface. Therefore, when the optical recording medium of the present invention is clamped in a drive, the recording layer has a "higher" position than a recording layer of a known DVD. The layer structure of the inventive optical recording medium is a key feature of reducing the thickness of the disc in an area of the recording layer. In particular, a thickness T 1 of only 0.4 to 0.7 mm is possible while remaining the reliability of the optical recording medium (i.e. without reading problems in most or all drives). Further, it is achieved that the optical recording medium may have only one substrate, i.e. only one dies of polycarbonate, whereas the other side of the recording layer is only covered by a protective lacquer. With that, manufacturing of the inventive optical recording medium is facilitated and more cost-efficient.
摘要(中):
本发明涉及DVD。 根据本发明,记录层相对于第二表面至少部分地或完全地定位在小于0.4mm的距离T 7。 因此,当将本发明的光记录介质夹在驱动器中时,记录层具有比已知DVD的记录层更高的位置。 本发明的光记录介质的层结构是在记录层的区域中减小盘的厚度的关键特征。 特别地,在保持光学记录介质的可靠性(即,在大多数或全部驱动器中没有读出问题)的情况下,厚度T 1 <1>仅为0.4至0.7mm是可能的。 此外,实现了光记录介质可以仅具有一个基板,即仅一个聚碳酸酯模,而记录层的另一侧仅被保护漆覆盖。 由此,本发明的光记录介质的制造便利且更具成本效益。
