摘要： Disclosed herein is a super resolution optical disc. The super resolution optical disc comprises dielectric layers, and a mask layer formed between the dielectric layers, in which the mask layer is constructed as a complex mask layer comprising a metallic oxide (MOx) or metallic nitride (MNy), and a metallic thin film formed thereon. A size of the cavities and an amount of metallic particles in cavities created by illumination of recording laser can be controlled to increase a level of a reproduction signal for recording marks and to enhance the quality of the reproduction signal.

摘要： A recording method for a phase change optical disk is disclosed. To prevent crystalline material from growing at the leading portion of predetermined marks, e.g. marks 4T or more in length, the interval between the first pulse and multi pulses among write pulses for forming marks 4T or more in length is increased by delaying the multi pulses against a reference clock and the widths or levels of the multi pulses are also increased. In another embodiment, to prevent a change in the starting positions of marks due to the increase of the interval between the first pulse and multi pulses, the last pulse among write pulses for forming marks 3T or more in length is advanced by a predefined time period. In still another embodiment, the interval between the first pulse and multi pulses among write pulses for forming marks 4T or more in length is increased and the starting position of the first pulse, the starting position and width of the last pulse, a trailing edge cooling time deviation are individually adjusted depending on the length of marks.
摘要翻译：公开了一种用于相变光盘的记录方法。为了防止结晶材料在预定标记的引导部分生长，例如，在长度上标记为4T或更大，通过将多个脉冲相对于参考时钟延迟并且多个脉冲的宽度或电平是多个脉冲，来增加用于形成长度为4T或更大的标记的写脉冲之间的第一脉冲和多脉冲之间的间隔也增加了。在另一个实施例中，为了防止由于第一脉冲和多脉冲之间的间隔的增加引起的标记的起始位置的变化，用于形成长度为3T或更大的标记的写脉冲之间的最后脉冲提前预定时间期。在又一个实施例中，用于形成长度为4T或更大的标记的写脉冲之间的第一脉冲和多脉冲之间的间隔增加，并且第一脉冲的起始位置，最后脉冲的起始位置和宽度，后沿冷却时间偏差根据标记的长度单独调整。

In the multi-layer super resolution optical disc, at least two recording layers, each of which comprises at least two mask layers and impact absorption layers formed between the mask layers, are laminated, and intermediate layers of polymer thermo-set by ultraviolet rays are formed between the recording layers. Accordingly, jitter characteristics for recording marks are improved, and recording density is enhanced.
