RCA 74,245 ABSTRACT OF THE DISCLOSURE A cutterhead assembly suitable for forming a topographic signal representative pattern in a recording media, such as a disc substrate, is constructed having a base member, a piezoelectric element and a cutting stylus. The piezoelectric element in this structure is asymmetrically assembled to the base member to reduce phase modulation of the recorded signal which would otherwise occurr from the transverse motion of the stylus during the cutting operation.
