Abstract

PURPOSE:To obtain excellent playback signals by clamping and fixing an annular piezoelectric element, to which a couple of magnetic heads are adhered, while sandwitching it between a fitting base having two projection parts along a main symmetric surface and a couple of fixing members each having a projection part in the center. CONSTITUTION:Magnetic heads 26 and 28 for normal reproduction are positioned accurately and fixed to an upper cylinder 46 with screws 47. Magnetic heads 30 and 32 for special reproduction, on the other hand, are positioned accurately and adhered onto a piezoelectric element 2. A piezoelectri-element fitting base 48 has two projections 68 and 70 along a main symmetric surface. At the center parts of fixing members 50 and 52, projection parts 56 and 58 of the same size and in the same size and in the same shape with a couple of projection parts 68 and 70 of the fitting base 48 are provided and at their parts, grooves 80 and 82 and holes 60 and 62 are made. The piezoelectric element 2 is sandwitched between the fitting base 48 and a couple of fixing members 50 and 52 and clamped uniformly with small screws 54 and after they are fixed by injecting an adhesive through the holes 60 and 62, the body is fixed to the upper cylinder 46 with small screws 66. Thus, excellent playback signals are obtained.
