  • Track change-over mechanism for a multi-channel tape recorder
    Patent number: 4107750
    Abstract: A track change-over mechanism for shifting a magnetic head of a multi-channel tape recorder and comprising a cam follower for moving the magnetic head and bearing upon a stepped cam angularly displaceable with an idler wheel carried on a pivoted lever which rocks to a driving position in which the idler wheel is in driving contact with capstan means for rotating the idler and the stepped cam, an electromagnetic device for directly or indirectly actuating rocking of the pivoted lever and means including a second cam for disengaging the idler wheel drive when the stepped cam has shifted the stepped cam-follower, and thereby the magnetic head, by one step.
