<p>PURPOSE:To record a cue signal independently of tape speed by changing the frequency and the recording time of the cue signal in accordance with tape running speed and recording them. CONSTITUTION:A control signal read out from a control head 1 is amplified by an amplifier 2, inputted to a speed detecting section 3, and it is detected that how many times as much as ordinary speed tape speed is. A system controller 4 sends information about a tape running direction to a cue signal generation circuit 5, generation order and generation time of a sine wave and mute is decided to generate based on information of this signal and information from the detecting section 3. Also, frequency of the sine wave is multiplied by a variable multiplication circuit 6, a frequency dividing value in a frequency dividing period is calculated based on speed information from the detecting section 3 and a cue signal from the controller 4. Since this cue signal is amplified by an amplifier 8 and the result is supplied to an auxiliary sound recording head 9, the cue signal can be recorded even at the time of specific reproducing independently of tape speed.</p> |
