摘要： Increase of jitter in a phase change optical recording medium is suppressed with no extreme decrease in the crystallization speed of the recording layer when the medium is overwritten at a high linear velocity. In addition, in a disk-shaped medium operated at a constant angular velocity, the overwriting is accomplished with the increase of jitter suppressed over the entire area of the medium. Provided is an optical recording method for recording a disk-shaped optical recording medium having a phase change recording layer which is rotated at a constant angular velocity, wherein amorphous recorded marks are formed in the recording layer. In this method, the minimum recorded mark is formed such that WL/ML incrementally or gradually decreases from the radially inner side to the radially outer side of the optical recording medium, when the minimum signal has a length of SL, and when the minimum recorded mark corresponding to said minimum signal has its maximum width of MW, EW is 0.1 MW; the position on the leading edge side of the recorded mark at the width of EW is designated effective leading edge; and the position on the trailing edge side of the recorded mark at the width of EW is designated effective trailing edge; the distance between the effective leading edge and the effective trailing edge is designated effective length ML; and the distance between the effective leading edge and the position at which the width starts to decrease on the trailing edge side is designated WL.

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： An improvement in production of an optical recording medium of phase change type is provided. In the present method, the step of repeated recording and erasing which had to be carried out after initialization and before shipment in the conventional process is eliminated. The optical recording medium produced by the present process retain good properties after repeated overwriting. In the process of the present invention, the prior art initialization step is replaced by modification treatment and the subsequent crystallization treatment. The modification treatment is a step wherein non-crystalline recording layer formed by sputtering is melted and cooled to change the crystal-lographic state into a non-crystalline state which is different from the non-crystalline state immediately after the formation of the recording layer. The crystallization treatment is a step conducted after the modification treatment wherein the recording layer in non-crystalline state is heated for crystallization.
