Claims

[Scope of utility model registration request]

In a recording and reproducing apparatus that forms a predetermined recording track on the recording medium or reproduces information recorded on the recording track by relative movement between the recording medium and the head, a first electro-mechanical conversion One end of the element is sandwiched between a second pair of electro-mechanical transducers and supported in a cantilever manner, while a head mounting member is connected to the free end of the first electro-mechanical transducer, and the head mounting member is connected to the free end of the first electro-mechanical transducer. A support device for a head in a recording/reproducing apparatus, characterized in that the head is attached to a mounting member, and further, a part of the electrode of the holder of each of the first and second electromechanical transducers is removed.
