COMPATIBLE OPTICAL PICKUP AND OPTICAL INFORMATION STORAGE MEDIUM SYSTEM EMPLOYING THE SAME |
摘要 |
An optical pickup compatible with different types of optically recorded media and an optical recording and/or reproducing system employing the compatible optical pickup, the compatible optical pickup including: a short wavelength light source emitting a short wavelength light; a low-density optical system emitting a long wavelength light; an objective lens focusing lights incident from the long wavelength light source and the low-density optical system onto an information storage medium; a single photodetector (PD) receiving the short and long wavelength lights reflected from the information storage medium; a detection lens focusing the short and long wavelength lights reflected from the information storage medium as a light spot onto the single PD; a first collimating lens positioned on an optical path of a light reflected, wherein the optical path is positioned between the objective lens and the single PD; and a driving unit adjusting a position of the first collimating lens.
