Abstract
PURPOSE: To make an expensive magnetic scale plate needless, by recording the magnetic signal of a wave length approximately equal to a prescribed wave length onto a part of the recording part of the periodic magnetic signal and by reproducing the recorded magnetic signal by the reproducing head and by applying the reproduced signal to the recording head.
CONSTITUTION: Rotation axis 6 is provided rotatably in motor case 23 of the recording part of the magnetic signal of a magnetic body by bearing 24, and rotor disc 8, ring 9, yoke member 25, and magnets 26 and 27 are fixed to rotation axis 6 in one body to constitute a rotor. Coils 28 and 29 constituting a stator are provided oppositely to magnets 26 and 27 in the upper part of motor case 23. By this constitution, when a current is flowed to coils 28 and 29 to drive the motor, the above- mentioned rotor rotates, and therefore, not only the driving motor but also expensive master magnetic scale plate 4 can be omitted, so that the cost can be reduced.
