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： A multilayer optical recording medium is provided with a totally reflective first information layer provided on a substrate and a second information layer being a translucent information layer provided via a spacer layer. The second information layer is composed of a TiO2 layer, a first dielectric layer, a reflective film, a second dielectric layer, a recording film, and a third dielectric layer, all of which are laminated together in this order. The first dielectric layer is made of ZrO2, Cr2O3, and Al2O3, and has a refractive index in the range of 1.84 to 2.20.

摘要： A method for recording data in an optical recording medium according to present invention is constituted so that data are recorded in an optical recording medium including a light transmission layer and two recording layers by projecting a laser beam whose power is pulse-like modulated between a recording power and a bottom power lower than the recording power onto the optical recording medium from a side of the light transmission layer and forming recording marks having different lengths in the recording layers and that when a recording mark having a longer length than that of the shortest recording mark is to be formed in the recording layers by modulating the power of a laser beam using a single pulse, a time of raising the power of the laser beam to the recording power is delayed relative to a time of raising the power of the laser beam to the recording power when the shortest recording mark is to be formed. In the case of recording data in the optical recording medium in accordance with the thus constituted method for recording data in an optical recording medium, jitter of a reproduced signal obtained by reproducing the recorded data can be markedly reduced.
