Abstract

PROBLEM TO BE SOLVED: To highly accurately and rigidly bond and fix a disk substrate and a hub while restricting an increase in man-hours and facility investment. SOLUTION: The apparatus is provided with a base jig member 11 having a cylindrical projecting part 11c and a suction hole 11b coupled to a vacuum suction source 21, and a fixed jig member 12 having a central hole 12b and a light introduction guide hole 12e. An opening part 12c opened in an upper face 12d of the central hole 12b is schematically like a funnel, with a diameter slightly larger than that of the cylindrical projecting part 11c. The guide hole 12e has its one end part opened in the whole circumference of the central hole 12b. The base jig member 11 and fixed jig member 12 are combined by inserting the cylindrical projecting part 11c into the central hole 12b so that a gap communicating with the suction hole 11b is formed. An end part of a photoguide member 16 inserted in the guide hole 12e is arranged in a ring at the opening part 12c of the central hole 12b. Therefore, a suction part sucking and holding a disk substrate 2 and a ring-shaped projection part projecting ultraviolet rays are formed at the same point.

It is supported by the disk table of the device and is driven to rotate at high speed. Then, the information signal recorded in the information signal recording section is reproduced by the laser light emitted from the optical pickup device while the optical disc is rotationally driven at a high speed. In addition, an optical disk capable of recording an information signal is subjected to magnetic field modulation in accordance with an information signal to be recorded by an external magnetic field generator in a state where an information signal recording unit is irradiated with laser light emitted from an optical pickup device. A desired information signal is recorded by applying the external magnetic field.

And an outer peripheral flange portion. The fitting portion has an outer diameter substantially equal to the diameter of the center hole of the disk substrate, and is provided with a spindle shaft hole at the center thereof through which a spindle shaft of the disk rotation drive mechanism of the recording / reproducing apparatus passes. The outer peripheral flange portion has a slightly smaller diameter than the outer peripheral diameter of the inner peripheral holding portion of the disk substrate.

ディスクを廉価に製造することを可能とする。As described above in detail, according to the hub joining apparatus for a disk-shaped recording medium according to the present invention, the disk substrate and the hub are attracted and held in a state where they are centered with each other. An irradiation part for irradiating the applied adhesive with ultraviolet light is constituted by an opening of a center hole provided in a fixing jig member at the same position.
By irradiating ultraviolet rays simultaneously and uniformly over the entire circumference to the ultraviolet-curable adhesive applied to the disk substrate from the irradiating section, the adhesive is almost uniformly applied over the entire area in the circumferential direction. It can be cured in a uniform state.
Therefore, the hub joining apparatus performs a first ultraviolet irradiation step for temporarily joining the disk substrate and the hub in a state where they are centered with each other, and, as a subsequent step, the main joining of the disk substrate and the hub over the entire circumference. And a second ultraviolet irradiation step are performed at the same time, so that the steps can be streamlined and the equipment costs of an ultraviolet ray generator and a transport device can be reduced, so that a highly accurate optical disk can be manufactured at low cost.
