摘要： The multilayer optical recording medium with six or more recording and reading layers disposed one above the other has at least two or more recording and reading layer groups. The recording and reading layer groups each include a plurality of recording and reading layers successively disposed one above the other. The reflectance of each of the recording and reading layers in a stacked state decreases in the order from a front side near a light incident surface toward a back side far from the light incident surface. A recording and reading layer nearest the front side among the recording and reading layers in the recording and reading layer group nearer the back side has a reflectance in a stacked state higher than that of a recording and reading layer nearest the back side among the recording and reading layers in the recording and reading layer group nearer the front side.

摘要： An optical recording and reading method is provided in which the information necessary for recording and reading layers is quickly acquired to reduce the seek time during reading and recording. The optical recording and reading method is used for an optical recording medium that includes a plurality of recording and reading layers and a servo layer. Information is recorded on or read from the recording and reading layers by irradiating them with a recording and reading beam while the servo layer is irradiated with a servo beam to perform tracking control. When information is recorded on the recording and reading layers, control information necessary for subsequent recording and reading to be performed on the recording and reading layers is recorded on the servo layer 18. When the subsequent recording or reading is performed, the control information on the servo layer is consulted, and then the recording or reading is performed on the recording and reading layers.

摘要： In an evaluation device and an evaluation system, the level of base power is set higher than that in an optimal recording condition at a set room temperature and lower than the level of bias power. In particular, the level of the base power is set so that the jitter value of a recording mark and a blank, which is formed in a required high temperature environment, during reproduction in the high temperature environment becomes minimum. By evaluating the recording characteristic of a recording mark and a blank formed by irradiation of recording laser light in the form of a pulse train, the recording characteristic of an optical recording medium in high-speed recording in high temperature environment is evaluated.

摘要： An optical recording medium is provided, which has reduced degradation in jitter caused by manufacturing variations of a semiconductor laser emitting laser beams or variations in output power of laser beams, and which dissipates heat in the recording layer during recording by laser beams to increase the power margin of the laser beam providing playback jitter values at a certain level or less. An optical recording medium 10 has a support substrate 12, on which formed are a reflective film 16, a second dielectric layer 18, a recording layer 20, a first dielectric layer 22, a heat sink layer 24, and a light-transmitting layer 26. The heat sink layer 24 is formed of a material having a thermal conductivity within a certain range, e.g., alumina, to dissipate heat through the heat sink layer 24 when the heat is generated by a laser beam incident from the light-transmitting layer 26, thereby preventing an increase in temperature of the recording layer 20.
