Title: Compatible optical pick-up
Inventor: JUNG CHUNG IN
IPC: G11B7/1374
Filed: 2006-06-15
Abstract: A compatible optical pickup is provided to record and reproduce an optical disc independently by one device at high speed and to prevent a damage caused by shock by positioning a main component inside a deck. A compatible optical pickup comprises a light source(10), an objective lens(70), a beam splitter(30), a diffracting grating(40), a sensor lens(80), and an optical system. The light source emits light of predetermined wavelength. The objective lens collects the light sent from the light source on a recording layer of an optical disc. The beam splitter passes and reflects the light emitted from the light source or the light reflected from the recording layer of the optical disc. The diffracting grating passes and diffracts the light reflected and separated by the recording layer of the optical disc. The sensor lens generates a point at the light reflected from the optical disc. The optical system includes a detecting unit(90) detecting an information signal and an error signal by receiving the light collected by the sensor lens. The optical system consists of first and second optical systems which record and reproduce the optical disc with low density and high density, respectively. The second optical system is operated independently of the first optical system, while the second optical system shares a part of the first optical system selectively by a polarization converting element. The objective lenses of the first and the second optical system are positioned in a track direction of the optical disc at one actuator.
