Abstract
A system for automatically reproducing signals from predetermined recording locations on a magnetic disc based on a set program for automatic reproduction of the signals. The system comprises a discrimination circuit for discriminating a recorded signal at each predetermined recording position on the disc and a memory circuit for storing the discrimination results together with their track numbers. The system further comprises a program setting device for setting the automatic reproduction program and a checking circuit for checking the program with reference to the discrimination results stored in the memory circuit. The checking circuit causes a warning circuit to produce a noticeable warning when it is found that the set program is inconsistent with the records on the disc.
