TURNTABLE, A METHOD FOR MANUFACTURING THE SAME DEVICE, AND AN OPTICAL DISC DRIVE SYSTEM USING THE SAME DEVICE, CONCERNED WITH INSERT-INJECTION MOLDING A TURNTABLE BODY WITH A MAGNET INTEGRATEDLY

摘要

PURPOSE: A turntable, a method for manufacturing the same, and an optical disc drive system using the turntable are provided to manufacture a turntable by using an insert-injection process, thereby reducing the number of parts and the manufacturing cost. CONSTITUTION: The turntable comprises a body(20) and a magnet(30). The body(20) includes an axis portion(22) and a disc combination unit(24). The axis portion(22) has an axial combination hole combined with a motor shaft. The disc combination unit(24) is inserted into a hole of a disc. The magnet(30) is integratedly formed on the body(20). The body(20) is formed via an injection molding process while the magnet(30) is formed via an insert-injection molding process. The body(20) also includes a step(23) on an edge for enhancing a friction force with a disc, and a buffering function.
