[n: Merocyanine] [n0804] {g11b 7/247d} Patents (Class G9B/7.152)
  • Organic compound for recording layer for high speed recording of information and optical recording medium including the same
    Patent number: 7781044
    Abstract: A recording layer including a novel organic compound for a high density optical recording medium is provided. The information may be recorded on the recording layer at a 2× speed or higher speed with a relatively lower writing power so that heat distribution of the recording layer in the irradiated area is not likely to become steep both in time and space. The organic compound incorporated in the recording layer has the following general chemical structural formula (I).
