摘要： It is an object of the present invention to provide an optical recording medium that is suitable for recording information therein at a high velocity. An optical recording medium according to the present invention includes a recording layer formed of a phase change material and capable of recording data therein at a linear recording velocity equal to or higher than 10 m/sec, wherein Rtop satisfies the condition that it is larger than {11−(V/5)} and smaller than {22−(2V/5)}, where Rtop (%) is a reflectivity of the crystal phase change material forming the recording layer and V (m/sec) is a target linear recording velocity. According to the present invention, since modulation (MOD) of 50% or more can be ensured, it is possible to effectively suppress the degradation of jitter caused by recording data at a high linear recording velocity equal to or higher than 10 m/sec.

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： 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： In an optical information medium having an information bearing surface having projections and depressions and/or capable of forming recorded marks, a functional layer is added. The information borne on the information bearing surface can be read by using reading light of a wavelength longer than 4NA·PL wherein PL is the minimum size of the projections and depressions or the recorded marks and NA is the numerical aperture of a reading optical system, setting the power of the reading light within such a range that the functional layer does not change its complex index of refraction, and irradiating the reading light to the information bearing surface constructed by the functional layer or to the information bearing surface through the functional layer or to the functional layer through the information bearing surface. The medium enables reading at a high resolution beyond the diffraction limit.
