<p>In a rotary magnetic head drum assembly (1) lands (15) connected to signal lines of a rotary magnetic head drum (1) are, upon assembly of the unit, brought into contact respectively with the upper ends of upwardly extending spring pins (20a) of a plurality of spring pin connectors (20) mounted on a connector base plate (18) secured to the underside of a drum base (11) which supports a stationary magnetic head drum (3). In this way the spring pins (20a) which are connected to external amplifiers are electrically connected to the rotary magnetic head drum (1) when the stationary magnetic head drum (3) is mounted on the drum base (11). <IMAGE></p> |
