ABSTRACT:
In a magnetic tape recording and playback device, a resilient body is engaged with a head base. At the time of recording and playing back a tape, the head base is pressed and fixed when the resilient body is directly pushed by a lever, and at the time of withdrawing the head, the head base is directly driven by the lever, so that an engaging member of a main base is engaged with a pressing member, and the head base is pressed and fixed. In this way, a force given to the resilient body is reduced at the time of head base movement. It is possible to reduce the required head base drive force at the time of head base movement.
