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
