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.
