    • Disclosed is a peelable sheet (3) on which a stamper receiving layer (2) for the production of an optical recording medium is intended to be laminated. The peelable sheet (3) has a release agent layer (32) on a surface on which a stamper receiving layer (2) is to be laminated. The release agent layer (32) comprises: an olganopolysiloxane having an alkenyl group in its molecule (other than an MQ resin mentioned below); an alkenyl-containing MQ resin comprising an M unit represented by the formula (1) RR-Si-O-···(1) [wherein Rrepresents an organic group; and Rrepresents an alkenyl group] and a Q unit represented by the formula (2) as constituent units; and a cross-linking agent. The release agent layer (32) is formed by using a release agent substantially containing no particle comprising an organic substance. The MQ resin contains an alkenyl group in an amount of 0.5 to 5% by mass. The peelable sheet (3) can reduce concave defects on a convex-concave pattern transfer surface of a stamper receiving layer (2).

    • A super resolution optical recording medium is provided to prevent the degradation of reproducing signal so as to increase the number of times that information is able to be reproduced. A super resolution optical recording medium(20) comprises a substrate(21), a super resolution layer(24) formed on the substrate, and a recording layer(26) disposed on the lower or upper part of the super resolution layer. The super resolution layer is formed with a super resolution aperture having a size smaller than a resolution limit of an emitted beam incident on the super resolution layer. The recording layer is formed with a mark having a size at the resolution limit of the emitted beam or less when irradiated to a reaction temperature which is higher than the super resolution temperature.
    • 提供超分辨率光记录介质以防止再现信号的劣化,从而增加信息能够被再现的次数。 超分辨率光记录介质(20)包括基板(21),形成在基板上的超分辨率层(24)和设置在超分辨率层的下部或上部的记录层(26)。 超分辨率层由具有小于入射在超分辨率层上的发射光束的分辨率极限的尺寸的超分辨率孔径形成。 当记录层被照射到高于超分辨率温度的反应温度时,具有在发射光束的分辨率极限以下的大小的标记。
