Abstract

PURPOSE:To simplify the driving mechanism with a thin-gage structure, by providing the rotor having several magnets distributed in a circular form at the outer circumference of a record disk plus the stator containing the coils opposing to the magnets via a fixed space each. CONSTITUTION:The rotor containing the magnets 2 distributed in a circular form to secure an alternate arrangement of different magnetic poles is provided at the outer circumference of the record disk 1. Then the disk 1 is inserted to the groove part of the magnet 2, and at the same time the center hole of the disk 1 is fitted to the center shaft 4 to be held between the stabilizers 5a and 5b. The driving coils 9 opposing to the magnets 2 via the fixed space are provided to the base 6 to form the stator. Thus the rotor including the disk 1 is turned by giving a switch control to the current of the coil 9. As a result, a large torque can be obtained, at the same time simplifying the supporting mechanism. In such way, a small-size and thin-gage longitudinal player can be obtained.
