Problems solved by technology

[0007] However, since the assembly of the disc clamping device including the spring and the chuck member is small, it is difficult to assemble the disc clamping device precisely
When the disc clamping device is not assembled accurately, the spring and the chuck member are not arranged in the exact position, and as a result, the chuck member achieves being inserted into the chuck housing, but cannot return to its original position

Abstract

The invention discloses a disk chucking device and a motor device having the same. Disclosed is a disk chucking device. A disk chucking device according to an aspect of the invention may include: a chuck housing mounted on one surface of a rotor case being rotatable and having a receiving portion with an outside opening to be connected to a receiving space provided therein; and a chuck chip comprising an elastic plate being elastically transformed when a disc being mounted on the rotor case is inserted and securing an inter circumferential surface of the disc.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2010-0044175 filed with the Korean Intellectual Property Office on May 11, 2010, the contents of which are hereby incorporated by reference. technical field [0002] The present invention relates to a disk chucking device and a motor device having the disk chucking device, more particularly, to a disk chucking device for stably mounting a disk at a mounting position and a A motor device with the disc clamping device is provided. Background technique [0003] Generally, a spindle motor installed in an optical disc drive rotates the disc so that an optical pickup can read data recorded on the disc. [0004] Small, lightweight and thin optical disc drives are desired. In particular, for ultra-thin, tiny motors used in laptop computers, the size of the magnetic circuits used to drive these motors has been reduced. Therefore, various designs have been developed in order to generate a torque large enou...
