Title: Head assembly and recording medium driver
Inventor: MITA TAKESHI
IPC: H02N2/02
Filed: 2001-10-17
Abstract: PROBLEM TO BE SOLVED: To provide a head assembly in which the frequency band of electric signals to be supplied to piezoelectric actuators is further expanded. SOLUTION: Piezoelectric actuators 28 and 29 are used to establish a reference attitude of a head slider 21 while a voltage is not being supplied. When the voltage is applied, the tip parts 28b and 29b of the actuators 28 and 29 are pulled toward base section tips 28a and 29a. Thus, the actuators 28 and 29 generate a couple which changes the attitude of the slider 21 from the reference attitude in only one direction about the center of rotation CR. The moment of inertia generated by the slider 21 during its rotational motion is suppressed to a lower level compared with the rocking motion of the slider by the principle of a pendulum. The natural frequency of a vibrating system that is constituted of the slider 21 and the actuators 28 and 29 can be increased. Therefore, the frequency of servo signals is secured in a wider frequency band.
