Abstract

A disk manufacturing method that includes: processing a surface of a disk while rotating the disk; cleaning the surface of the disk after the processing to remove a processing residue from the disk; drying the disk after the cleaning; and end-face cleaning that cleans an end-face of the disk while rotating the disk, the end-face cleaning being performed concurrently with at least one of the processing and the cleaning.

Claims (32)

1 . A method for manufacturing a disk, comprising:

processing a surface of a disk while rotating the disk;

cleaning the surface of the disk after the processing to remove a processing residue from the disk;

drying the disk after the cleaning; and

end-face cleaning that cleans an end-face of the disk while rotating the disk, the end-face cleaning being performed concurrently with at least one of the processing and the cleaning.

2 . The method for manufacturing a disk according to claim 1 , wherein the end-face cleaning wipes out the residue from the end-face of the disk by bringing a tape into contact with the end-face of the disk.

3 . The method for manufacturing a disk according to claim 1 , wherein the end-face cleaning washes out the residue on the end-face of the disk by spraying a liquid on the end-face of the disk.

4 . The method for manufacturing a disk according to claim 2 , wherein the end-face cleaning washes out the residue on the end-face of the disk by spraying a liquid on the end-face of the disk.

5 . The method for manufacturing a disk according to claim 1 , wherein the processing further comprises polishing that polishes the surface of the disk by bringing a polishing material into contact with the surface of the disk while rotating the disk, and

the end-face cleaning is performed concurrently with the polishing.

6 . The method for manufacturing a disk according to claim 2 , wherein the processing further comprises polishing that polishes the surface of the disk by bringing a polishing material into contact with the surface of the disk while rotating the disk, and

the end-face cleaning is performed concurrently with the polishing.

7 . The method for manufacturing a disk according to claim 3 , wherein the processing further comprises polishing that polishes the surface of the disk by bringing a polishing material into contact with the surface of the disk while rotating the disk, and

the end-face cleaning is performed concurrently with the polishing.

8 . The method for manufacturing a disk according to claim 1 , wherein the cleaning further comprises a tape cleaning that sprays a liquid on the surface of the disk after the processing and roughly cleans the residue on the surface of the disk by bringing a tape into contact with the surface of the disk while rotating the disk, and

the end-face cleaning is performed concurrently with the tape cleaning.

9 . The method for manufacturing a disk according to claim 2 , wherein the cleaning further comprises a tape cleaning that sprays a liquid on the surface of the disk after the processing and roughly cleans the residue on the surface of the disk by bringing a tape into contact with the surface of the disk while rotating the disk, and

the end-face cleaning is performed concurrently with the tape cleaning.

10 . The method for manufacturing a disk according to claim 3 , wherein the cleaning further comprises a tape cleaning that sprays a liquid on the surface of the disk after the processing and roughly cleans the residue on the surface of the disk by bringing a tape into contact with the surface of the disk while rotating the disk, and

the end-face cleaning is performed concurrently with the tape cleaning.

11 . The method for manufacturing a disk according to claim 1 , wherein the cleaning further comprises scrubbing that sprays a liquid on the surface of the disk and scrubs the surface of the disk by bringing a scrubbing material into contact with the surface of the disk while rotating the disk, and

the end-face cleaning is performed concurrently with the scrubbing.

12 . The method for manufacturing a disk according to claim 2 , wherein the cleaning further comprises scrubbing that sprays a liquid on the surface of the disk and scrubs the surface of the disk by bringing a scrubbing material into contact with the surface of the disk while rotating the disk, and

the end-face cleaning is performed concurrently with the scrubbing.

13 . The method for manufacturing a disk according to claim 3 , wherein the cleaning further comprises scrubbing that sprays a liquid on the surface of the disk and scrubs the surface of the disk by bringing a scrubbing material into contact with the surface of the disk while rotating the disk, and

the end-face cleaning is performed concurrently with the scrubbing.

14 . The method for manufacturing a disk according to claim 1 , wherein the cleaning further comprises high-frequency cleaning that sprays the surface of the disk with a liquid imparted with a high-frequency oscillation and washes out the residue on the surface of the disk while rotating the disk, and

the end-face cleaning is performed concurrently with the high-frequency cleaning.

15 . The method for manufacturing a disk according to claim 2 , wherein the cleaning further comprises high-frequency cleaning that sprays the surface of the disk with a liquid imparted with a high-frequency oscillation and washes out the residue on the surface of the disk while rotating the disk, and

the end-face cleaning is performed concurrently with the high-frequency cleaning.

16 . The method for manufacturing a disk according to claim 3 , wherein the cleaning further comprises high-frequency cleaning that sprays the surface of the disk with a liquid imparted with a high-frequency oscillation and washes out the residue on the surface of the disk while rotating the disk, and

the end-face cleaning is performed concurrently with the high-frequency cleaning.
