    摘要： An optical disc having pits shorter in length than 0.40 .mu.m, with the ratio of the width of the shortest pit to that of the longest pit being not less than 0.8, is formed by forming a master disc by light exposure using a light source having a wavelength not shorter than 350 nm. By taking advantage of the fact that the pit width A looking from the reflective film 20 of the optical disc is deceased to be smaller on forming the reflective film 20 than the pit width B looking from the disc substrate 10 by a value equal to the film thickness, a row of pits, generally broader than the pit width optimum when looking from the side oft the disc substrate 10, is formed on light exposure on the master disc using the laser light having a wavelength not smaller than 350 nm. The reflective film 20 is formed on the row of pits transcribed from the master disc to the disc substrate 10 to provide a pit width which minimizes the inter-pit interference or jitter of the playback RF signals. The signals are read out from the side of the reflective film 20, that is from the side of the light-transmitting layer 30, instead of from the light-transmitting layer 30.

    摘要： Disclosed is an information recording medium capable of, in the case of recording information signals such as high density information, sufficiently transferring the information signals, and suppressing resonance upon high speed rotation and enhancing the durability of the medium. The medium includes a substrate, a recording layer provided on the substrate for recording an information signal, and a light transmission layer laminated on the recording layer, wherein an information signal is recorded or reproduced on or from the medium by making light incident on the medium from the light transmission layer side. The substrate includes a core layer made from a resin, and a surface layer made from a resin and integrated with the core layer. The surface layer has on its one side plane information signals in the form of irregularities on the recording layer side and has a fluidity which is larger than that of the core layer in the case where both the surface layer and the core layer are in a molten state at the same temperature.
