Optical recording medium having in a static mode, a flexible region extending to 1/3 of the recording area

摘要

An optical recording medium with a circular body including a substrate, a recording layer and a dielectric layer on the substrate, the circular body having a recording/reproducing area and a hub attached to a surface of the circular body. When the circular body stands vertically, the recording/reproducing area of the hub-attached surface is curved in a convex form, and the flexural amount is from 5 mum to 100 mum.
