Abstract

PURPOSE:To simplify structure and assembling work by bonding several magnetic heads to one stuck piezoelectric element. CONSTITUTION:Two magnetic heads 38 and 40 are bonded not to individual piezoelectric elements but to the same surface of one stuck piezoelectric element 52, which serves as a rotary cylinder. Therefore, the dispersion of displace characteristics of two magnetic heads 38 and 40 based upon the characteristic dispersion of piezoelectric 52 never occurs and a circuit applying electric energy to piezoelectric element 52 requires only one system. In this way, high precision can be obtained and structure and its fabrication can be simplified.
