PURPOSE:To disperse friquency distribution by obtaining >= 2 kinds of mechanical vibration characteristics by making a difference in shape between a guide arm with a reading and writing heak and another guide arm with a servo head. CONSTITUTION:Guide arms 10 and 11 each have a projection part 14 which comes into contact with a carriage body 4, and is drawn to a carriage body 4 side by the engaged piece 16 of the carriage body 4 in an engaging hole 15 and a screw 17. In at least >= 2 of guide arms 10 for reading and writing and guide arms 11 for servocontrol, holes 18 differing in shape are formed. |
