Title: Optical scanning device
Inventor: ISHIZAKA SATORU
IPC: H04N1/113
Filed: 1998-03-04
Abstract: PROBLEM TO BE SOLVED: To provide the optical scanning device which generates no interference fringes even when making an optical scan on a recording medium having a transparent protection layer on the surface. SOLUTION: The optical scanning device which scans the scanned surface 10a having the protection layer 13 on the surface with luminous flux is equipped with a light source which emits luminous flux and such an optical system that the optical scanning surface formed by the scan with the luminous flux slants at a specific angle to the normal of the scanned surface 10a.  Consequently, direct incident light which reaches a recording layer after passing through the protection layer 13 and twice-reflected light which reflected by the border surface between the protection layer 13 and recording layer and further reflected by the border surface between the protection layer 13 and an external field to reach the recording layer are generated, bu those direct incident light and twicereflected light have deviation corresponding to the specific tilt of the scanned surface, so that no interference fringes are formed.
