20080250435 | Optical disk apparatus - An optical disk apparatus is disclosed which includes a first printed circuit board, on which a first circuit pattern is formed; a rotor, on which an optical disk may be placed, and which is electrically connected with the first circuit pattern; a second printed circuit board, which is stacked adjacent to the rotor on a surface of the first printed circuit board, and on which a second circuit pattern is formed; a sensor unit, which is mounted on the second printed circuit board in electrical connection with the second circuit pattern, and which is configured to sense a rotation of the optical disk; and a support plate, which supports the first printed circuit board and the rotor. In this optical disk apparatus, a separate printed circuit board can be utilized to support the sensor unit, whereby manufacturing costs can be reduced and working efficiency can be improved. | 10-09-2008 |
20090119690 | Disk chucking device and disk driving device having the same - A disk chucking device and a disk driving device having the same are disclosed. The disk chucking device may include: a chuck base, on which a boss is formed; chuck chips inserted in the chuck base in a manner such that the chuck chips protrude out from the chuck base; an elastic member, which elastically supports a pair of adjacent chuck chips towards an outer side of the chuck base; and a protrusion portion, which is formed on a bottom of the boss, and which supports the elastic member. The disk chucking device can improve the environment of the elastic members that support the chuck chips, to improve the alignment between the rotation centers of the disk and the chuck base. | 05-07-2009 |
20100153981 | DISK DRIVE - A disk drive is disclosed. The disk drive can include includes a spindle motor, which can rotate a disk; an encoder, which can detect the rotational speed of the disk; an encoder holder, which secures the encoder; and a base plate, which supports the spindle motor, and in which a holder indentation is formed for inserting the encoder holder in. Certain embodiments of the invention allow easy height adjustments for the encoder holder, so that the encoder may maintain a particular distance from the disk, and also allow the encoder to be fitted onto the base plate, even in cases where the base plate has a limited mounting area. | 06-17-2010 |
20130207499 | ROTOR ASSEMBLY FOR MOTOR AND SPINDLE MOTOR INCLUDING THE SAME - There are provided a rotor assembly for a motor and a spindle motor including the same.
