Abstract

PURPOSE:To offer an optical card inclination detecting device for detecting an inclination of an optical card without adding a special optical system, by constituting said device so that an inclination angle of the optical card against the relative moving direction of an optical head can be detected by monitoring the variation quantity of a tracking signal. CONSTITUTION:In an optical card processor for recording or reproducing the information to and from an information recording track by bringing an optical head 6 to a relative movement against an optical card, and also, displacing the optical head 6 in the direction orthogonal to the relative moving direction by a tracking signal and allowing it to follow the information recording track, an optical card inclination detecting device 100 is provided with a servo-circuit 101, an optical system 102, and an actuator 103. In such a state, a tracking signal (b) for driving the actuator 103, based on a tracking error signal (a) inputted to the servo-circuit 101 is generated. By monitoring the variation quantity of this tracking signal (b) by using a differentiating circuit 104, an inclination angle of the optical card against the moving direction of the optical card is detected.
