Claims

[Scope of utility model registration request]

A crosstalk removal device for a recorded information reproducing device that removes crosstalk by adjusting the incident angle of an information reading light beam onto an information recording medium, the device comprising a slider that is movable along a predetermined axis; , a holding member that holds a pickup that emits the information reading light beam and is pivotably supported to the slider, and a driving means that drives the holding member to swing, the slider swingably supported by the predetermined shaft;
A crosstalk removal device for a recorded information reproducing device, characterized in that the incident angle is adjusted by adjusting the swing angle of the slider.
