In an optical information recording medium having at least two information
layer, guide grooves for tracking or sample pits or information pits
corresponding to information signals are formed on a surface of a first
substrate. A first information layer formed by a thin film for reflecting
a portion of a light beam made incident on the first substrate and
permitting penetration of a portion of the light beam is formed on a
surface of the first substrate. Guide grooves for tracking or information
pits corresponding to information signals are formed on a surface of a
second substrate. A second information layer having a reflectance higher
than that of the first information layer is formed on a surface of the
second substrate. Between the first information layer and the second
information layer, there is formed a transparent separation layer for
positioning the first information layer and the second information layer
to be spaced a predetermined distance apart from each other.
