ABSTRACT:
A transducer element assembly comprises a transducer element having a scanning surface for scanning a recording surface of a recording medium, a cantilever having the transducer element provided on a free tip end thereof and having a pair of holes provided on a root end thereof, a support part having a pair of generally conical pivots, and a magnetic coupling mechanism provided on the cantilever and on the support part for magnetically coupling the two by a magnetic attraction or repulsion. The cantilever is detachably mounted on the support part and is user replaceable. When the cantilever is mounted on the support part, the pivots engage the corresponding holes and the cantilever is rotatable about the root end thereof in a direction approximately perpendicular to the scanning surface of the transducer element. The magnetic attraction or repulsion generated by the magnetic coupling mechanism acts with a predetermined magnitude in a predetermined direction so that the transducer element makes contact with the recording surface of the recording medium with a predetermined contact pressure.
