ABSTRACT:
A crosstalk level detector has a processing circuit for determining the level of crosstalk of a signal read by an information reproducing system from an information storage medium with information recorded in its tracks. The processing circuit compares levels of reference signal components contained in the read signal and produced from adjacent signal tracks at positions aligned in a direction normal to the tracks, and calculates the crosstalk level based on the compared levels. The reference signal components may be derived from a signal recorded in the information stored medium, such as a horizontal synchronizing signal recorded in an optical video disk.
