发明名称 Power conserving motor control circuit for a video tape recorder
摘要 A battery-operable video tape recorder includes a rotary magnetic head which during normal operation is driven at a predetermined speed controlled by a servo circuit. In the pause mode of the recorder the rotary magnetic head is driven at a lower, uncontrolled speed to reduce power consumption. Release of the pause mode may be delayed until the servo circuit has locked following a pause.
