A method of manufacturing an optical information recorded disc. The method includes steps of forming a light-absorbing layer and a protective layer on a substrate, irradiating a laser through the substrate on the light-absorbing layer to form reproducible information which can be reproduced by a reproducible signal satisfying a standard of a compact disc.

A method for manufacturing an optical information recorded disc having an information stored therein and reproducible by an optical means, the method comprising the steps of: (a) preparing a discoidal light-transmitting substrate having tracking guide means on one surface; (b) forming a light-absorbing layer on the surface of the light-transmitting substrate, wherein an optical parameter represented by rabsdabslabs is the real part of the complex refractive index of the light-absorbing layer, dabs is the thickness of the light-absorbing layer and l0.05≥r0.6, and the imaginary kabs of the complex refractive index of the light absorbing layer is at most 0.3; (c) forming a light-reflecting layer on the light-absorbing layer; (d) forming a protective layer on the light-reflecting layer; and (e) irradiating the light-absorbing layer through the light-transmitting substrate and along the tracking guide means with a laser.
