Abstract
A method of manufacturing an optical disk on which light-emitting regions for absorbing a laser beam and emitting light of a wavelength different from that of the laser beam and reflection regions for reflecting a laser beam irradiated thereon are alternately arranged, comprises the steps of forming a reflection layer on a transparent substrate, forming a plurality of through holes in the reflection layer, and filling a light-emitting layer consisting of a fluorescent member in the through holes, thereby a high density optical disk can be manufactured.
Claims6
A method of manufacturing an optical information recording disk on which light-emitting regions for absorbing a laser beam and emitting light of a wavelength different from that of the laser beam and reflection regions for reflecting a laser beam irradiated thereon are alternately arranged, the method comprising the steps of:
- forming a reflection layer on a transparent substrate;
- forming a plurality of through holes in the reflection layer;
- and
- filling a light-emitting member in the through holes.
An optical information recording disk comprising;
- a transparent substrate;
- a reflection layer formed on one flat main surface of said substrate having a track of a plurality of minute through holes formed thereon;
- a light-emitting member with which said through holes are filled, said light-emitting member absorbing a laser beam and emitting a light of a wavelength different from that of the irradiated laser beam.
