Abstract

There is provided a disc chucking device. A disc chucking device according to an aspect of the invention may include: a chuck housing having an opening communicating with a mounting space therein; a chuck member having one end portion exposed to an outside of the opening; and a spring member mounted within the mounting space in order to exert an elastic force to the chuck member, wherein a portion of an outer circumferential surface of the chuck housing, on which the chuck member is disposed, has a smaller outer diameter than other portions thereof.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2009-0095082 filed with the Korean Intellectual Property Office on October 7, 2009, the disclosure of which is hereby incorporated by reference. technical field [0002] The present invention relates to a chuck device and a motor device having the chuck device, and more particularly, to a chuck device for stably mounting a disc in a mounting position and a motor having the chuck device device. Background technique [0003] Generally, a spindle motor installed inside an optical disc drive rotates the disc so that an optical pickup can read data recorded on the disc. [0004] Small, light and thin hard drives are now required. Specifically, for ultra-thin, tiny motors used in notebook computers, the magnetic circuit used to drive the motor is also reduced. Therefore, various designs have been implemented to generate sufficient torque for rotating the disc and to ensure stable rotation of the disc. ...
