- FIG. 1 to FIG. 3 are views for explaining a drawing method and its device in this embodiment.
- FIG. 1 is a conceptual diagram showing a principle method of peeling a disk substrate.
- An adhesive R is interposed between the two disk substrates, whereby the disk substrates D 1 and D are in a bonded state (see FIG. 1 (A)).
- the upper disk substrate is made of, for example, PMMA (polymethyl methacrylate) and has a metal film D11 formed by sputtering
- the lower disk substrate is made of polycarbonate and has a similar metal film. It is assumed that D 21 is formed.
- a gap S is generally formed around the center hole of both disc bases because the adhesive is not filled with the adhesive, and air is blown into such a gap to prevent peeling. It gives a start.
- the two disk substrates are pulled apart by the pressure of the blown air, so that they can be peeled off evenly, and the pulling force (separation force) is partially biased as in the past.
- the upper and lower disk substrates themselves are directly bonded to the part of the inner periphery where the metal film is not sputtered between the two disk substrates before the drawing is performed, and the adhesive R Are adhered, and the adhesive R is also adhered to the outer peripheral end.
- This adhesive dust is discharged to the outside together with the blown air from the peripheral edge of the disk base.
- the discharged adhesive dust R 1 easily pollutes the surroundings, and easily penetrates into mechanical devices, causing a failure.

- a circumferential protrusion 11 is provided at the peripheral end of the cradle 1, and it is preferable that the discharged air collides with this portion once.
- the circumferential projection 11 prevents the air containing the adhesive dust R 1 from vigorously escaping outward.
- a negative pressure source (first negative pressure source) for suction is located at another place (not shown), and is connected to the suction groove 31 through the negative pressure passage 32.
- the receiving table 1 also has suction holding means 4 for holding the disk base by suction on the surface of the receiving table, and the suction holes 41 are different from the negative pressure source 33 (the first negative pressure source). It is connected to another negative pressure source (not shown) through a negative pressure channel 42.
- the optical disc D is placed on the cradle 1.
- the center hole H of the optical disc D is mounted on the boss 2 of the cradle 1 and placed.
- This blowing causes a separation force in the vertical direction to act to cause separation between the two disk substrates, which propagates from the center to the periphery.
- the suction groove 31 can be provided on the circumferential convex portion 11 of the receiving table.
- suction groove is shown as a continuous slit-like example, it can be an intermittent isolated opening.
