Title:
FEED CIRCUIT OF BIAS AC SIGNAL AND ERASING AC SIGNAL FOR TAPE RECORDER
Document Type and Number:
Japanese Patent JPS5938910
Kind Code:
A
Abstract:
PURPOSE: To always ensure good sound recording characteristics, by providing a generating circuit of bias AC signal and a generating circuit of erasing AC signal.
CONSTITUTION: The output signal generated from a bias AC signal generating circuit A is supplied to a sound recording head Hr as well as to input terminals (c) and (d) of an erasing AC signal generating circuit B. Thus an erasing AC signal having the same frequency as the bias AC signal is generated from the circuit B and supplied to an erasing head He1 or He2. As a result, it is possible to feed both bias and erasing AC signals to sound recording and erasing heads independently and in a stable form. Thus, the good sound recording characteristics are always ensured.
