Document Type and Number:
Japanese Patent JP2006039303
Kind Code:
A
Abstract:
To provide an optical information recording medium excellent in durability at a low cost in which information can be easily recorded in high information density.
The optical information recording medium contains a diamond like carbon (DLC) layer (2) deposited on a substrate (1). Information is recorded in the optical information recording medium by irradiating a selected recording spot region in a plurality of recording spot regions with an energy beam (5) so as to increase the refractive index of the DLC layer (2) in the recording spot region.
