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.

Dependent claims

A signal reproducing apparatus comprising:

movable head means;
moving means for sequentially moving said head means to different recording positions with respect to the recording surface of a record bearing medium;
detection means, responsive to an output of said head means, for detecting a type of information recorded at each recording position on the medium by reproducing the information recorded on the medium, the recorded information including two different types of information comprising video information and audio information;
memory means for storing indicia regarding the type of information detected by said detection means at each recording position;
program setting means for setting a program for sequentially reproducing information from predetermined recording positions on the medium in accordance with a reproducing order manually set in said program setting means;
recording heads for recording the program set by said program setting means onto the medium through said head means;
checking means for comparing the program set by said setting means with the indicia stored in said memory means, before reproducing begins;
reproducing means for reproducing the information recorded on the medium according to the program set by said program setting means;
and
reproducing control means for controlling the reproducing operation of said reproducing means based on the comparison performed by said checking means.
