摘要: A system for positioning a transducing head in disc drive device over selected track of rotatable includes an actuator arm which is about axis, suspension mechanism connected to the arm, and slider carrying supported by mechanism. low resolution motor moves axis effect coarse movement between tracks disc. piezoelectric element embedded distort fine head. Control circuitry distributes electrical signals selectively control thereof. The removing predetermined amount material from bonding resulting space it arm.
