Abstract

PURPOSE:To obtain a high-density information recording carrier with excellent signal precision, by forming a magnetic layer surface, which is the signal surface of a disk, directly by a stamper. CONSTITUTION:On the surface of a stamper A having a signal to be transferred, a peeling-agent layer 5 is formed and on it, a magnetic body layer 2 is formed; after a carrier base 3 is further formed, the stamper A is separated from the peeling-agent layer to obtain a disk product. For a disk on the optical system, a metallic layer is provided as a reflecting layer instead of the said magnetic body layer.
