ABSTRACT:
A head unit having a recording and/or reproducing head mounted on a resilient plate and having a contact surface which is brought into contact with a disc-like recording medium by depressing at a point which is located on the contact surface side remote from the center of displacement of the resilient plate. This arrangement prevents oscillation of the head caused by disequilibrium between the pressure of the contact surface of the head and sliding resistance of the recording medium during recording or reproducing, so that stable recording and/or reproducing is performed.
