Abstract

PURPOSE: To achieve the improvement in tracking and jitter characteristics by varying the antiresonance frequencies in the longitudinal and transverse directions of a cantilever thereby eliminating the mutual effects of the resonance modes in the longitudinal and transverse directions at the antiresonance points.
CONSTITUTION: Both or either one of cantilever body 5 or 6 is formed in such construction (e.g., plate form) in which it is easy to bend in a longitudinal or transverse direction, so that the stiffness of the cantilever body when viewed from the stylus tip differs in the longitudinal and transverse directions. Equally good results may also be obtained by making the stiffness of a spring part 4 viewed from the stylus tip at the values differing in the longitudinal and transverse directions. Since this stabilizes the contact relation between the stylus and recording disc, tracking and jitter characteristics may be improved.
