Abstract
Provided is a tilt adjusting apparatus of an optical disc drive for adjusting a tilt of an optical pickup unit. The tilt adjusting apparatus includes an optical pickup unit moving in a radial direction of the disc, along first and second guide shafts. The tilt adjusting unit also includes a fixing support unit that fixes the first guide shaft and an adjustment supporting unit that supports the second guide shaft and enables the height of both ends of the second guide shaft to be adjusted.
Claims19
A tilt adjusting apparatus of an optical disc drive, the tilt adjusting apparatus comprising:
- a pickup base;
- first and second guide shafts installed in the pickup base;
- an optical pickup unit configured to tilt and move along the first and second guide shafts in a radial direction of a disc configured to receive light emitted from the optical pickup unit;
- a fixing support unit that supports ends of the first guide shaft at a fixed height;
- and
- an adjustment supporting unit supporting ends of the second guide shaft and being configured to adjust a height of the ends of the second guide shaft;
- and
- wherein the optical pickup unit comprises at least one objective lens, and an actuator driving the at least one objective lens, and
- the actuator comprises
- a blade supporting the at least one objective lens, and
- a first coil disposed at sides of the blade in the radial direction of the disc to allow the blade to perform focusing driving and radial tilt driving.
