摘要： It is an object of the present invention to provide a method for recording data in an optical recording medium which can record data in a write-once type optical recording medium at a high linear recording velocity using a laser beam whose recording power is set low. The method for recording data in an optical recording medium according to the present invention is constituted so that data are recorded by a laser beam whose power is modulated in accordance with a pulse train pattern onto an optical recording medium including a substrate, a first recording layer, a second recording layer and a light transmission layer to form a recording mark wherein a recording pulse is divided into (n−1) divided pulses and the power of the laser beam is set to a recording power Pw at the peak of each of the divided pulses and set to a first bottom power Pb1 and the levels of the recording power Pw and the first bottom power Pb1 are determined so that a ratio Pb1/Pw of the first bottom power Pb1 to the recording power Pw falls within a range of 0.1 to 0.5. When the power of a laser beam is modulated using such a pulse train pattern to record data in an optical recording medium, the heating of a recording layer by the laser beam having the recording power Pw can be augmented by the laser beam having the first bottom power Pb1 and therefore, even in the case where data are to be recorded in an optical recording medium at a high linear recording velocity, it is possible to record data in the optical recording medium at a high linear recording velocity using a semiconductor laser having a low output.

摘要： In an optical recording medium wherein grooves or lands formed on the supporting substrate are used for the recording tracks, and wherein prepits are also formed, production of the supporting substrate and high density recording are facilitated. This medium comprises a supporting substrate and a recording layer on the substrate wherein the surface of the supporting substrate on which the recording layer is formed is formed with alternating continuous convex portions and continuous concave portions which are substantially parallel to each other. The adjacent continuous convex portions are connected by bridging convex portions extending in transverse direction, and the bridging convex portion has a planar configuration that its width is minimum at or near the center between the adjacent continuous convex portions. The supporting substrate is produced by using a master disk which has a resist layer formed with mother patterns of each of the continuous convex portions, continuous concave portions, and prepits. In the production of the master disk, the resist layer is intermittently irradiated with one exposure beam, and the area irradiated is used as the mother pattern of the continuous concave portions or convex portions, and the area which was not irradiated is used as the mother pattern of the prepits.

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.
