<p>PURPOSE:To enable consecutive recording without tracking distortion by controlling delay quantity so that phase difference can be fixed between the change point of an output signal from a frequency dividing means and the change point of an output signal from a delay means. CONSTITUTION:When the rotational phase of a capstan motor 5 is controlled by one capstan servo means 9, in a second capstan servo means 10, the delay quantity of the delay means is controlled by a first control means 103 so that the phase difference between the output signal from a delay means 101 and the output of a frequency divider 100 to divide the frequency of an output from a frequency generator 6. When a selecting means 11 is switched from the first capstan servo means 9 to the second capstan servo means 10, it is stopped by a second control means 102 to control the delay quantity with the first control means 103 and the delay quantity is fixed. Then, a capstan motor 5 is controlled by the second capstan servo means 10 with the output of the delay means as a reference so that the phase difference to the output of the frequency divider 100 can be fixed. Thus, consecutive recording can be executed while suppressing the tracking distortion.</p> |
