摘要： A method of recording data on a double-layer optical recording medium having a recording layer with high light transmittance is provided. A laser beam is modulated to emit a pulse series of laser including a write pulse of a write power and a cooling pulse of a bottom power, so as to encode and write data to be recorded as recording marks of a length nT along a track of the recording layer, where n is an integer and T is one clock cycle. An nT recording mark is formed using (n−1) write pulse(s), and when forming a recording mark of 4 T or longer, a cooling pulse with a pulse width of 0.8 T to 2 T is inserted before the last write pulse. Recording marks are thereby accurately formed without heat interference between consecutive recording marks and cross erase between recording marks of adjacent tracks.

摘要： An information recording method enables the precise formation of a recording mark on a recording layer having a high light transmittance such as an L1 layer of a double-layered optical recording medium. The information recording method uses the following recording strategy. A laser beam is pulse-modulated so as to create a pulse series including a write pulse of a recording power and a cooling pulse of a base power. Data to be recorded is modulated to have a length of a recording mark along a track of the recording layer. At the same time, the length of the recording mark is made to correspond to an integral multiple nT of T where T is one clock cycle. An nT recording mark corresponding to nT is recorded by using the same number of write pulses and cooling pulses when n is 4 or larger. Moreover, an average width AveTc for a single cooling pulse width Tc is set to satisfy: 1.0

摘要： To obtain an optical recording medium capable of recording at various recording transfer rates from a low speed to a high speed, by using a simple recording strategy.A recording layer 18 of a write-once optical recording medium capable of recording from a low speed to a high speed is formed by laminating a first sub recording layer 18A and a second sub recording layer 18B each containing a metal as its main component. When the recording layer (laminated recording layer) 18 is irradiated with a laser beam having a wavelength equal to or shorter than a blue wavelength by using a recording strategy comprising only a ratio of write power to bias power, the main component metals contained in the first and second sub recording layers 18A, 18B diffuse and are thus mixed together, forming the sub recording layers into a single layer by means of such mixing and forming recording marks whose reflectance have been irreversibly changed. Since the recording mark formation process does not need to select a recording strategy, it is possible to obtain many subordinate advantages such as a variable speed recording.

摘要： A write-once type optical recording medium is provided, which is low-cost and capable of maintaining the recording and reproducing stability high while enabling the relative ratio of read power to write power to be set high. The high-speed write-once type optical recording medium 10 includes a recording layer 18 that is constituted by laminating first and second subsidiary recording layers 18A and 18B each having one type of metal, for example Al and Sb respectively, as the main component. In the optical recording medium 10 having such constitution, the ratio between write power Pw and read power Pr, Pw/Pr is set to a value in the range of 2.0 to 8.0. When the recording layer 18 is irradiated with laser beam with a wavelength of 200 nm to 450 nm and a write power Pw of 2.5 to 5.0 mW at a recording-transferring rate of at least 35 Mps, Al and Sb contained in the subsidiary recording layers 18A and 18B respectively are diffused and mixed by the irradiation to form a recording mark that has a low reflectance, has been transformed to a single layer, and has been changed irreversibly.
