Abstract

To record an indicating signal on a record medium, the actuation of a cue signal recording switch is detected, and then the count of a cue signal cycle counter is sensed to determine if it has reached a preselected count. This counter is incremented by one count until the preselected count has been reached, whereupon it is reset to an initial count, and a cue counter is incremented by one count. Then, the count of the cue counter is sensed to determine if it is less than a particular count and, if so, a cue signal is recorded. If the cue count is not less than the particular count, the recording of the cue signal is terminated, thus representing one type of indicating signal. Recording of the cue signal continues until the cue counter reaches its particular count, even if the cue signal recording switch is deactuated. The foregoing steps are repeated substantially periodically in accordance with the programmed instructions of a processor. If the cue signal recording switch is re-actuated prior to the time that the cue counter reaches its particular count, the recording of the cue signal is interrupted for a predetermined duration, and then is resumed until the cue counter reaches a higher count, thus resulting in the recording of two bursts of cue signal to represent a second type of indicating signal. When the recorded cue signal is reproduced, the count of yet another counter is incremented even after the reproduced cue signal has terminated. If this count reaches a predetermined count, an indication of the first type of indicating signal is provided. However, if reproduction of the cue signal from the record medium resumes prior to the time that this counter reaches its predetermined count, an indication of the second type of indicating signal is provided.
