Abstract
PURPOSE: To improve the quality of reproducing and recording without requiring a complicated trouble by switching automatically a voltage, which is supplied to a capstan motor, so that the reproducing speed may be equal to the tape speed at a recording time.
CONSTITUTION: When data is recorded in a standard speed and is reproduced in the half speed, the output of binary output circuit 16 becomes L; and if selector switch 3 is switched to the NP-side contact by this output L, the supply voltage of capstan motor 2 becomes E1, and the speed is switched to the same standard speed as a recording time. Meanwhile, when data is recorded in the half speed and is reproduced in the standard speed, the output of binary output circuit 16 becomes H; and if selector switch 3 is switched to the SF-side contact by this output H, the voltage of capstan motor 2 becomes E2, and the speed is switched to the same half speed as a recording time. Thus, the voltage of the capstan motor is switched automaticlly, so that the quality of reproducing and recording can be improved.
