Abstract
A rotary head apparatus including a circuit board with an optimum and shortest distance between magnetic heads of the rotary head apparatus and a rotary transformer thereof. The members used in the present invention connect the above elements in a simple construction and positively transmitting signals can be reached. The rotary head apparatus comprises a first conductive member which is in contact with and electrically connected to lead terminals of a winding of a magnetic head and to an electronic circuit member. The circuit member is installed on the upper surface of the circuit board (the magnetic head side), which is mounted to a rotary drum equipped with the magnetic heads. A second conductive member is connected to the electronic circuit member and is in contact with and is electrically connected to lead terminals of a winding of a rotor of a rotary transformer. It is possible to arrange the circuit board with an optimum and shortest distance between the magnetic heads and the rotary transformer to connect these elements in a simple construction and to transmit signals with a high degree of certainty and with reduced transmission losses without being badly affected by oscillations, etc.
