| 20110047563 | SPINDLE MOTOR HAVING A CHUCKING MEMBER - A spindle motor is disclosed, wherein a spindle motor includes a rotating shaft coupling to a rotor yoke for supporting an optical disc, a clamp case disposing on the rotor yoke and coupling to the rotating shaft; and a chucking member including a rim portion combined with the clamp case, a plurality of extension portion radically extruded from an edge portion of the rim portion, and chucking arm portions formed at each of the end portion of the extension portions to chuck an inner face of the optical disc. | 02-24-2011 |
| 20110055858 | SPINDLE MOTOR - Disclosed is a spindle motor including a rotor yoke coupled with a rotation axis and having an optical disk mounted thereon; a clamp case that is arranged on the rotor yoke, inserted into an inner side of the optical disk and has a receiving groove formed on the side thereof; and a chuck clip having one side fixed to the clamp case corresponding to the receiving groove and the other side that elastically supports the inner side of the optical disk, the other side being corresponding to the one side. | 03-03-2011 |
| 20110158080 | Disc Clamp and Spindle Motor Having the Same - Disclosed is a disc clamp including a disc clamp body having a rotational axis hollow engaged with a rotational axis; a first disc balancer that is projected from the disc clamp body in the horizontal direction and formed in a first thickness A; and a second disc balancer that is bent downwards from an end of the first disc balancer in order to fix the disc and formed in a second thickness B, wherein an angle formed between a horizontal surface of the first disc balancer and the second disc balancer is from 92° to 95°. | 06-30-2011 |
| 20110219390 | Integrated Disk Driving Module - An integrated disk driving module is disclosed, the module including a base unit including a stepping motor fixture bent from an upper plate toward an accommodation space, wherein the stepping motor fixture is integrally formed with the upper plate, and a stepping motor rotatably fixed to the stepping motor fixture. | 09-08-2011 |
| 20110219391 | INTEGRATED DISK DRIVING MODULE - An integrated disk driving module is disclosed, the module including a base unit including a spindle motor fixture including an opening-formed upper plate, a lateral surface plate bent from the upper plate to form an accommodation space, and a spindle motor fixture concavely formed from the upper plate toward the accommodation space, wherein the spindle motor fixture is integrally formed with the upper plate; and a spindle motor fixed inside the spindle motor fixture to rotate a disk. | 09-08-2011 |
| 20110219392 | INTEGRATED DISK DRIVING MODULE - An integrated disk driving module is disclosed, the module including a base unit formed with a first motor fixture concavely formed on an upper plate, and a second motor fixture bent from the upper plate in opposition to the first motor fixture, wherein the first and second motor fixtures are integrally formed on the upper plate; a spindle motor secured inside the first motor fixture to rotate a disk; and a stepping motor rotatably secured to the second motor fixture. | 09-08-2011 |
| 20110239238 | Integrated Disk Driving Module - An integrated disk driving module is disclosed, the module including a base unit including an opening-formed upper plate, a lateral surface plate bent from an edge of the upper plate to form an accommodation space, and a stepping motor fixture bent from the upper plate toward the accommodation space, wherein the stepping motor fixture is integrally formed with the upper plate; and a stepping motor including a lead screw and a pivot member arranged at a distal end of the lead screw and coupled to the stepping motor fixture, and wherein the stepping motor fixture is formed with an insertion groove into which the pivot member is secured, where width of the insertion groove is larger than a diameter of the pivot member. | 09-29-2011 |
| 20110239239 | Integrated Disk Driving Module - An integrated disk driving module is disclosed, the module including a base unit including an opening-formed upper plate, a lateral surface plate bent from an edge of the upper plate to form an accommodation space, and a first motor fixture concavely formed from the upper plate to the accommodation space, and a second motor fixture bent from the upper plate to the accommodation space, wherein the first and second motor fixtures are integrally formed to the upper plate; a spindle motor fixed inside the first motor fixture to rotate a disk; a stepping motor rotatably fixed to the second motor fixture; a circuit substrate arranged at the base unit to be electrically connected to the spindle motor and the stepping motor, and encoder module including an encoder base coupled to an encoder opening formed at the upper plate of the base unit, an encoder coupled to a through hole of the encoder base to sense revolution of the disk, and an encoder circuit substrate electrically connected to the encoder and coupled to the encoder base; and a connector including at least one conductor for electrically connecting the circuit substrate and the encoder circuit substrate, and an insulation member securing the conductor. | 09-29-2011 |
