摘要： PROBLEM TO BE SOLVED: To reduce a pitching vibration of movable section and simultaneously improve the driving sensitivity of an objective lens driving apparatus for driving objective lens in radial tilting direction in addition to focusing direction and tracking direction.
SOLUTION: Tracking coils 5R and 5L are attached to the external sides of two focusing coils 4R and 4L. A first magnet 10 and a second magnet 11 are respectively arranged within the focusing coils 4R and 4L. A third magnet 12 is arranged to face the first magnet 10 and the second magnet 11 across the tracking coils 5R and 5L. An open end of a first yoke 6 for holding the first magnet 10 and an open end of a second yoke 7 for holding the second magnet 11 are coupled by a bridging yoke 9. Since magnetic flux is formed in the bridging yoke 9, the pitching vibration can be suppressed. Also, effective magnetic flux is increased and therefore the driving sensitivity is improved.

摘要： PURPOSE: To make it possible to change driving states between two-phase excitation driving and micro-step driving smoothly at high speed, by changing first and second current patterns at an equal point of instantaneous currents of these first and second current patterns. CONSTITUTION: A stepping motor 3 made up of a rotor 6 and stators 7a and 7b is used for moving a carriage body. A driving device 21 for the stepping motor has a driving means for selectively generating a first current pattern, in which the rotor 6 is rotated in the stators 7a and 7b on a first pitch and a second current pattern, in which the rotor 6 is rotated on a second pith. When both instantaneous currents of first and second current patterns are equal, the driving means changes the first and second current patterns for feeding the current to the stators 7a and 7b. Then, the driving states between two-phase excitation driving and the micro-step driving are changed smoothly at high speed.
