Abstract

PURPOSE:To realize the high-accuracy recording of the video signals, aural signals and others by growing the overcoat layers on the upper surface of the concavity caused by etching as well as on the recording layer on the substrate. CONSTITUTION:Etching layer 2 of the silicon dioxide or the like is provided on substrate 1 along with installation of recording layer 3 of the photo resist or the like. In this case, etching stopper layer 9 featuring the etching resistance performance is provided preferably between substrate 1 and layer 2. The development process and others are given after forming the pit pattern to layer 3, and then the etching is given to layer 2 with use of layer 3 as the mask to form the concavity. On the surface of such signal recording board, overcoat layers 6 and 6' are formed with the fixed thickness each via the formation enable material and through the vapor growth method. The height of layers 6 and 6' are set larger than the thickness of layer 2. Owing to the stage error between these overcoat layers, the accuracy is increased for signal pit 5'. Thus the high-accuracy recorded disk can be formed.
