摘要： An optical information recording medium is here disclosed which comprises a transparent substrate, a recording layer comprising an organic dyestuff on which information can be written by a laser beam, a reflective layer and a protective layer formed in this order on the substrate, the aforesaid optical information recording medium being characterized by containing a pit·edge control agent for the formation of recording pits, particularly a dyestuff thermal decomposition accelerator in the recording layer. By the addition of the pit·edge control agent, deviation properties and jitter properties can be remarkably improved, whereby a CD-R medium having a low error rate and good recording properties can be provided. In consequence, stable compatibility with a commercial CD player can be secured.

摘要翻译： 这里公开了一种光学信息记录介质，其包括透明基板，包含有机染料的记录层，其上可以通过激光束来写入信息，反射层和在该基板上依次形成的保护层，上述光学 信息记录介质的特征在于包含用于在记录层中形成记录凹坑，特别是染料热分解加速剂的凹坑控制剂。 通过添加pit.edge控制剂，可以显着提高偏差特性和抖动特性，从而可以提供具有低误码率和良好记录性能的CD-R介质。 因此，可以确保与商业CD播放器的稳定的兼容性。
