Abstract

PURPOSE:To obtain a high-quality still picture by providing two sets of head pairs in which two magnetic heads of different azimuth angles to the magnetic head device and thus reproducing the signals of the same track continuously. CONSTITUTION:Conductor substrate 3-2 is attached each across piezoelectric element 3-1 and then stuck in two sheets with the reverse polarity to each other in order to secure the bimorph structure. One end of the substrate is fixed via fixing tool 3-6, and magnetic head 3-9 featuring a different azimuth from magnetic head 3-7 is mounted to the other end of the substrate respectively. In this case, head 3-9 is made to touch magnetic tape 3-8. The deflecting voltage applied to element 3-1 is controlled, and as a result the relative position between heads 3-7/3-9 and tape 3-8 can be controlled so as to trace on the record track. Thus only the same track can be reproduced continuously with the heads featuring the coinciding azimuth angle in the case of the still reproduction, obtaining a high-quality still picture.
