Title:
DEVICE FOR ELECTROMECHANICALLY RECORDING SIGNAL INFORMATION
Document Type and Number:
Japanese Patent JPS57101499
Kind Code:
A
Abstract:
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 occur from the transverse motion of the stylus during the cutting operation.
