    • 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.
    • 一种旋转磁头装置,包括在旋转磁头装置的磁头与其旋转变压器之间具有最佳且最短距离的电路板。 本发明中使用的构件以简单的结构连接上述元件,可以达到正向信号。 旋转头装置包括与磁头的绕组的引线端子和电子电路部件接触并电连接的第一导电部件。 电路构件安装在电路板(磁头侧)的上表面上,该表面安装到装有磁头的旋转磁鼓上。 第二导电构件连接到电子电路构件,并且与旋转变压器的转子的绕组的引线端子接触并电连接。 可以以简单的结构将电路板与磁头和旋转变压器之间的最佳和最短的距离布置成电路板,并以高度的确定性和较低的传输损耗传输信号,而不会受到严重的影响 振荡等
