<p>PURPOSE:To eliminate superposed recording and non recording parts by counting the number of pulses accompanied by the reverse rotation of a capstan at the time of the stoppage of a capstan motor and calculating the number of pulse counts for aligning the phase at the start time of a linked recording including the result of this count as well. CONSTITUTION:At the time of the linked recording of a magnetic tape utilizing the pulse (FG pulse) of the frequency oscillator provided on a capstan motor shaft, the reverse rotation of the capstan at the stoppage time of a capstan motor is detected based on two kinds of FG pulses S2, S3 by the frequency oscillator. A calculating means 1 counts the number of the FG pulses S2, S3 accompanied by the detected reverse rotation of the capstan and calculates the number of counts of the FG pulse for aligning the phase at the linked recording starting time including this counted result. A superposed recording is thus eliminated and the generation of an unrecording part can be prevented as well.</p> |
