Title: Method and apparatus for inspecting surface of disk
Inventor: TAKAHASHI IPPEI
IPC: G11B7/26
Filed: 1988-09-09
Abstract: PURPOSE:To shorten a defect detecting time without decreasing the defect detecting sensitivity of a disk by scanning the disk for the entire diameter with a light beam, turning the disk during the scanning by one half, and receiving the transmitted light or the reflected light from the entire scanned region with a wide pipe shaped receiver. CONSTITUTION:A light beam 12 is projected on a disk 11 from a scanner 10, and scanning is performed. A scanning line 13 is drawn on the disk 11 with the tip of the light beam 12. The scanning line 13 is set so as to pass a central point C of the disk 11. The light beam is reflected from the disk 11 and advances to a wide pipe shaped receiver 17. The beam is received with a light guiding rod 18. Optoelectronic transducing operation is performed in an optoelectronic transducer 19 in correspondence with the amount of the received light. Since the scanning line 13 covers the diameter of the disk 11, the detection of the defect in the disk 11 is finished during the turning of the turntable 13 by one half. Thus the defect detecting time can be shortened.
