Abstract
PURPOSE:To make off-track quantity small by fixing a magnetic member constituting a voice coil motor to a carriage block and inserting a plate for making frictional force small. CONSTITUTION:When the magnet member 7 constituting the voice coil motor is fixed to the carriage block 9, the small plates 13 and 14 of which frictional factor is small is inserted between them to make the magnetic member 7 to be easily slided. One end of the magnetic member 7 is regularly fixed by a screw 10 and the other end is tightened with prescribed torque of which degree makes the magnetic member 7 to be begun to be slided by a screw 11. A belleville spring is used as locking. Therefore, accompanied with the change of temperature, the magnetic member 7 can be slided in a seek direction. Thus, the off-track come from the difference of coefficient of thermal expansion caused by the difference of the material between the magnetic member 7 and the carriage block 9 can be actually eliminated.
