Abstract

PURPOSE:To smoothly perform consecutive recording without generating phase shift, by performing sample-holding by holding the level of a capstan trapezoidal wave signal at a midpoint compulsorily at the time of moving a mode from an assembling mode to a recording mode. CONSTITUTION:A capstan trapezoidal wave generating means 19 which generates the capstan trapezoidal wave signal (CTP signal), a frequency division means 25 which generates a capstan frequency division signal (CPG signal), and a sample/hold circuit 20 which performs the sample-holding of the CTP signal, etc., are provided. The output level of the capstan trapezoidal wave generating means 19 is set at the midpoint level of a normal CTP signal according to the migration of the mode from the assembling mode to the recording mode after the arrival of a first CPG signal, and the CTP signal is generated. In such a way, it is possible always to set the midpoint of the capstan trapezoidal wave at an initial value in the recording mode and to realize the consecutive recording smoothly in spite of the frequency of the CPG signal without generating the phase shift.
