Title:
STAMPER INSPECTING ADHESIVE SHEET AND STAMPER INSPECTING METHOD
Document Type and Number:
Japanese Patent JP2008041165
Kind Code:
A
Abstract:
To provide an optical disk capable of efficiently recording a visible image having high contrast by the use of laser light.
In a stamper inspecting adhesive sheet, where an adhesive layer containing an adhesive agent is formed on an optical film, the adhesive agent has 3 (N/25 mm) or smaller for the adhesive force. In a stamper inspecting method, with which a stamper is irradiated with laser light, to perform inspection by using its reflected light, the stamper surface to be inspected to which the stamper inspecting adhesive sheet is stuck is irradiated with the laser light.
