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. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) Apparatus according to claim 1, further comprising: means for controlling said recording means in accordance with a checking result by said checking means. ### Claim 3 (depends on 2) Apparatus according to claim 2, further comprising: warning means for producing warning in response to an output of said checking means which indicates that the set program is inconsistent with the indicia stored in said memory means. ### Claim 4 (depends on 1) Apparatus according to claim 1, further comprising: warning means for producing a warning in response to an output of said checking means which indicates that the set program is inconsistent with the indicia stored in said memory means. ### Claim 5 (depends on 1) Apparatus according to claim 1, further comprising: display means for displaying a stored content of said memory means. ### Claim 6 (depends on 1) Apparatus according to claim 1, wherein said detection means includes a discrimination circuit for discriminating whether a signal is recorded based on the output of said head means. ### Claim 7 (depends on 1) Apparatus according to claim 1, wherein the information recorded on the medium includes a video signal and an audio signal; and wherein said detection means includes a discrimination circuit for discriminating which of the video signal and the audio signal is recorded based on an output of said head means. ### Claim 8 (depends on 1) Apparatus according to claim 1, wherein said memory means is arranged to store the indicia regarding the recording at each recording position together with an identification thereof as a result of the detection by said detection means. ### Claim 9 A reproducing and recording apparatus for performing at least one of reproducing and recording a plurality of information in a recording medium, comprising: search means for searching the recording condition of the information on the recording medium by reproducing the plurality of information recorded on the recording medium; storing means for storing a result of the search; program setting means for setting a reproducing sequence of an automatic reproduction for the information recorded in the recording medium; checking means for checking the reproducing sequence set by said setting means based on the stored content in said storing means; and recording means for recording the reproducing sequence set by said program setting means on the recording medium. ### Claim 10 (depends on 9) A reproducing apparatus according to claim 9, further comprising prohibiting means for prohibiting the recording of said reproducing sequence when said checking means detects that the reproducing sequence is inconsistent with the stored content of said storing means. ### Claim 11 (depends on 9) A reproducing apparatus according to claim 9, further comprising warning means for producing a warning when said checking means detects that the reproducing sequence is inconsistent with the stored content of said storing means. ### Claim 12 (depends on 9) A reproducing apparatus according to claim 9, further comprising display means for displaying the stored content of said storing means. ### Claim 13 A reproducing apparatus for reproducing a plurality of types of information in a recording medium, comprising: search means for searching the recording condition of the information on the recording medium by determining types of information recorded on the recording medium; storing means for storing a result of the search; manual program setting means for manually setting a reproducing sequence of an automatic reproduction for the information recorded in the recording medium; checking means for checking whether the reproducing sequence set by said manual program setting means is suitable by comparing the reproducing sequence with the stored content in said storing means; and recording means for recording the reproducing sequence set by said manual program setting means on the recording medium. ### Claim 14 (depends on 13) A reproducing apparatus according to claim 13, further comprising prohibiting means for prohibiting recording of the reproducing sequence when said checking means detects that the reproducing sequence is inconsistent with the stored content of said storing means. ### Claim 15 (depends on 13) A reproducing apparatus according to claim 13, further comprising warning means for producing a warning when said checking means detects that the reproducing sequence is inconsistent with the stored content of said storing means. ### Claim 16 (depends on 13) A reproducing apparatus according to claim 13, further comprising display means for displaying the stored content of said storing means. ### Claim 17 A reproducing and recording method for performing at least one of reproducing and recording a plurality of information in a recording medium, said method comprising the steps of: searching a recording condition of the information on the recording medium by reproducing the plurality of information recorded on the recording medium; storing a result from said searching step in storing means; setting a reproducing sequence of an automatic reproduction for the information recorded in the recording medium; checking the reproducing sequence set in said setting step based on the stored content in the storing means; and recording the reproducing sequence set in said setting step on the recording medium. ### Claim 18 (depends on 17) A reproducing and recording method according to claim 17, further comprising a step of prohibiting said recording step of recording the reproducing sequence when, in said checking step, the reproducing sequence is detected to be inconsistent with the stored content of the storing means. ### Claim 19 (depends on 17) A reproducing and recording method according to claim 17, further comprising a step of producing a warning when, in said checking step, the reproducing sequence is detected to be inconsistent with the stored content of the storing means. ### Claim 20 (depends on 17) A reproducing and recording method according to claim 17, further comprising a step of displaying the stored content of the storing means.
