Abstract
Provided are an optical disc drive and method for driving the optical disc drive. The method includes transporting a disc to a chucking position where a spindle is positioned using a loading roller, blocking power transferred from a loading motor to the loading roller, and chucking the disc on the spindle using power from the loading motor. Accordingly, damages to the disc caused by chucking may be prevented.
Claims14
A method of driving an optical disc drive including a loading roller, a loading motor providing power to the loading roller, and a power train system transferring power between the loading motor and the loading roller, the method comprising:
- transporting a disc to a chucking position where a spindle is located, via the loading roller;
- blocking power from the loading motor to the loading roller in response to transportation of the disc being completed;
- and
- chucking the disc on the spindle using the power transmitted from the loading motor.
An optical disc loading device comprising:
- a loading motor;
- a loading roller that is driven by the loading motor and which loads and unloads a disc;
- a power train system that is disposed between the loading motor and the loading roller and which comprises a plurality of gears;
- and
- a power switching system that is disposed in the power train system and which controls a power transfer path between the gears.
An optical disc drive, comprising:
- an optical pickup assembly comprising a spindle on which a disc is mounted, and an optical pickup module;
- a loading motor providing power to load the disc;
- a loading roller transporting the disc in a direction of the spindle;
- a power train system that is disposed between the loading motor and the loading roller and which includes a plurality of gears;
- and
- a power switching system that is included in the power train system and which controls a power transfer path between the gears.
