Title:
MANUFACTURING METHOD FOR INFORMATION RECORDING MEDIUM, AND BOARD STRIPPING JIG
Document Type and Number:
WIPO Patent Application WO/2014/002702
Kind Code:
A1
Abstract:
Provided is a manufacturing method for an information recording medium which is capable of shortening discharge time of a fluid when stripping a glass substrate from a polishing platen after a polishing step. A manufacturing method for an information recording medium that is provided with a glass substrate (1) having a main surface, and a magnetic thin-film layer formed upon the main surface of the glass substrate (1), is provided with steps for: pressing, upon the polishing surface of the platen, the glass substrate (1) so as to polish the main surface thereof; and stripping the glass substrate (1) from the polishing surface using a board stripping jig. The board stripping jig has a nozzle (21) which discharges compressed air (A), and a contact surface (27) which comes into tactile contact with the glass substrate (1) which moves in the surface direction of the polishing surface by way of the compressed air (A), and includes a positioning unit (26) which defines a position for the glass substrate (1), and a board receiving unit (25) which receives and holds the glass substrate (1) which floats from the polishing surface by way of the compressed air (A).
