    • The present invention relates to a writable optical record carrier and a method of writing information on such a writable optical record carrier. The record carrier comprises a substrate carrying a recording stack which recording stack comprises, in this order, a recording layer and an absorption layer. The recording layer is essentially transparent for an incident light beam, and comprises material which changes its optical characteristics when heated. The first absorption layer converts the incident beam to heat thereby indirectly changing the optical characteristics of the recording layer material. The method comprises the steps: positioning a writing unit at a predetermined position, generating the beam by means of the writing unit, at least partially absorbing the beam in the first absorption layer, thereby producing a first spot of heat, conducting the heat towards the recording layer, and thereby locally changing the optical characteristics of the recording layer material.
    • 本发明涉及一种可写入光学记录载体和在这种可写入的光学记录载体上写入信息的方法。 记录载体包括承载记录堆叠的基板,记录堆叠依次包括记录层和吸收层。 记录层对于入射光束基本上是透明的,并且包括当加热时改变其光学特性的材料。 第一吸收层将入射光束转换成热,从而间接改变记录层材料的光学特性。 该方法包括以下步骤:将写入单元定位在预定位置,通过书写单元产生光束,至少部分地吸收第一吸收层中的光束,从而产生第一热点,将热量传导到 记录层,从而局部地改变记录层材料的光学特性。
