Abstract
A positioning device and method includes a motor having a rotation axis, a driver for driving the motor on the basis of control information, a detector for detecting position information of the rotation axis of the motor, and a digital signal processor for performing an operation on the control information in accordance with the position information detected by the detector.
Claims6
A positioning device comprising:
- an actuator, having a magnetic material portion to be temporarily magnetized by conduction of electricity, for abutting an object;
- abutting means for causing said actuator to abut the object;
- detecting means for detecting a movement position of said actuator;
- conducting means for causing said magnetic material portion of said actuator to conduct electricity when said actuator is located within a predetermined range set by the detection of said detecting means to fix said actuator to the object;
- and
- write-in means for writing control information of the object on a medium when said actuator is fixed to the object.

A method for positioning a subject comprising the steps of:
- moving an actuator having a magnetic material portion to be temporarily magnetized by conduction of electricity so as to abut the subject;
- detecting a setting position of said actuator;
- controlling a position of the subject by causing the magnetic material portion of said actuator to conduct electricity in accordance with the setting position detected in said detecting step to fix said actuator to the subject;
- and
- writing control information of the subject on a medium when said actuator is fixed to the subject.
