Disk bonding system

A disk fabricating system for forming a single disk by bonding first and second disks, said system comprising:

• an adhesive supplying section for supplying a liquid adhesive to the first disk:
• a disk handling section for arranging the first and second disks in a confronting state in which the first and second disks confront each other and the adhesive supplied to the first disk is interposed between the first and second disks, and for transferring the first and second disks so that the first and second disks remain in the confronting state;
• and
• a coating section for receiving the first and second disks from the disk handling section, and spreading the liquid adhesive between the first and second disks by a centrifugal force;
• wherein said disk handling section comprises a disk holding member for holding the first and second disks in the confronting state in which the first and second disks are spaced apart from each other and the first and second disks confront each other, and for maintaining the confronting state while said disk handling section transfers the first and second disks to said coating section.

A disk fabricating process for forming a single disk by bonding first and second disks, said system comprising:

• an adhesive supplying step for supplying a liquid adhesive to the first disk;
• a disk handling step for arranging the first and second disks in a confronting state in which the first and second disks confront each other and the adhesive supplied to the first disk is interposed between the first and second disks, and for transferring the first and second disks so that the first and second disks remain in the confronting state;
• and
• a coating step for receiving the first and second disks after the disk handling step, and spreading the liquid adhesive between the first and second disks by a centrifugal force;
• wherein said disk handling step comprises a disk holding operation for holding the first and second disks in the confronting state in which the first and second disks are spaced apart from each other and the first and second disks confront each other, and for transferring the first and second disks to said coating section while maintaining the confronting state.

• wherein said disk handling step comprises:
• a second disk gripping step of gripping the second disk;
• a second disk transferring step of transferring the second disk to a position just above the first disk;
• a clearance adjusting step of adjusting a clearance between the fist and second disk by moving the first and second disks relative to each other along a vertical direction;
• and
• a first disk gripping step of gripping the first disk so that the first and second disk confront each other.
